The maximum displacement from the equilibrium that the mass will attain. The maximum displacement is 75 .67 cm _ . Formula used: The governing equation of a mass-spring system is: F e x t = [ i n e r t i a ] y ″ + [ d a m p i n g ] y ′ + [ s t i f f n e s s ] y = m y ″ + b y ′ + k y Consider F e x t = 0 . In the case of underdamped, b 2 − 4 m k < 0 and there will be two complex conjugates to the associated auxiliary equation. For the roots α ± i β , the general solution that determines the motion will be y ( t ) = e α t ( C 1 cos β t + C 2 sin β t ) . The solution form can also be expressed as y ( t ) = A e α t sin ( β t + ϕ ) , where A = C 1 2 + C 2 2 and tan ϕ = C 1 C 2 . The constant A is called the amplitude, A e α t is the damping constant, ϕ is the phase angle, the quasiperiod is P = 2 π β and the quasifrequency is 1 P . Calculation: Given that, mass 1 4 kg is attached to a spring with stiffness 8 N/m and the damping constant is 1 4 N-sec/m . That is, m = 1 4 , k = 8 and b = 1 4 . Thus, the governing equation of a mass-spring system F e x t = m y ″ + b y ′ + k y for 0 external force becomes, 1 4 y ″ + 1 4 y ′ + 8 y = 0 . Multiply by 4 to obtain y ″ + y ′ + 32 y = 0 . The associated auxiliary equation is, r 2 + r + 32 = 0 . Factorize r 2 + r + 32 = 0 using quadratic formula − b ± b 2 − 4 a c 2 a as, r = − 1 ± ( 1 ) 2 − 4 ( 1 ) ( 32 ) 2 ( 1 ) = − 1 ± 1 − 128 2 = − 1 ± − 127 2 = − 1 ± 127 i 2 ( ∵ i = − 1 ) = − 0.5 ± 0.5 127 i That is, the roots are r 1 = − 0.5 + 0.5 127 i and r 2 = − 0.5 − 0.5 127 i . Here, α = − 0.5 and β = 0.5 127 . Thus, the solution form y ( t ) = e α t ( C 1 cos β t + C 2 sin β t ) becomes y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) . Given that, the mass is moved 1m to the left from the equilibrium and released. That is, y ( 0 ) = − 1 and y ′ ( 0 ) = 0 . The negative sign indicates the left direction. Apply the initial conditions to obtain the value of the constants as follows: Substitute t = 0 and y ( 0 ) = − 1 in y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) , y ( 0 ) = e − 0.5 × 0 ( C 1 cos ( 0.5 127 × 0 ) + C 2 sin ( 0.5 127 × 0 ) ) − 1 = C 1 cos ( 0 ) + C 2 sin ( 0 ) C 1 ( 1 ) + C 2 ( 0 ) = − 1 C 1 = − 1 Differentiate y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) with respect to t as, y ′ ( t ) = [ e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) ) − 0.5 e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) ] = [ e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) ) + e − 0.5 t ( − 0.5 C 1 cos ( 0.5 127 t ) − 0.5 C 2 sin ( 0.5 127 t ) ) ] Simplify as, y ′ ( t ) = e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) − 0.5 C 1 cos ( 0.5 127 t ) − 0.5 C 2 sin ( 0.5 127 t ) ) = e − 0.5 t ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 t ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 t ) ) Substitute t = 0 and y ′ ( 0 ) = 0 in y ′ ( t ) = e − 0.5 t ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 t ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 t ) ) , y ′ ( 0 ) = e − 0.5 × 0 ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 × 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 × 0 ) ) 0 = ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0 ) 0 = ( − 0.5 127 C 1 − 0.5 C 2 ) ( 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) ( 1 ) 0.5 127 C 2 − 0.5 C 1 = 0 Since C 1 = − 1 , the above equation becomes, 0.5 127 C 2 − 0.5 ( − 1 ) = 0 0.5 127 C 2 = − 0.5 C 2 = − 0.5 0.5 127 C 2 = − 1 127 That is, C 1 = − 1 and C 2 = − 1 127 . Thus, the solution y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) becomes, y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) . The aim is to find the which maximum displacement. Note that, the maximum displacement will be obtained at y ′ = 0 . Differentiate y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) with respect to t as, y ′ ( t ) = [ e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) − 0.5 127 127 cos ( 0.5 127 t ) ) − 0.5 e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) ] = [ e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) − 0.5 cos ( 0.5 127 t ) ) + e − 0.5 t ( 0.5 cos ( 0.5 127 t ) + 0.5 sin ( 0.5 127 t ) ) ] Simplify further as, y ′ ( t ) = e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) + 0.5 sin ( 0.5 127 t ) ) = 0.5 ( 127 + 1 ) e − 0.5 t sin ( 0.5 127 t ) Thus, y ′ = 0 implies, 0.5 ( 127 + 1 ) e − 0.5 t sin ( 0.5 127 t ) = 0 e − 0.5 t sin ( 0.5 127 t ) = 0 Note that, the value of the exponential is never zero. Thus, the only possibility is sin ( 0.5 127 t ) = 0 . This happenes only when 0.5 127 t = n π . Simplify further as, t = n π 0.5 127 . The first value is obtained when n = 1 . Thus, n = 1 implies t = π 0.5 127 . On simplification, t = 2 π 127 . That is, the maximum displacement occurs at t = 2 π 127 . Substitute t = 2 π 127 in y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) , y ( 2 π 127 ) = e − 0.5 × 2 π 127 ( − cos ( 0.5 127 × 2 π 127 ) − 1 127 sin ( 0.5 127 × 2 π 127 ) ) = e − π 127 ( − cos ( π ) − 1 127 sin ( π ) ) = e − 0.2788 ( 1 − 1 127 ( 0 ) ) = 0.7567 ( 1 − 0 ) = 0.7567 That is, the maximum displacement is 0.7567m. In other words, 75.67cm. Therefore, the maximum displacement is 75 .67 cm _ .

The maximum displacement from the equilibrium that the mass will attain. The maximum displacement is 75 .67 cm _ . Formula used: The governing equation of a mass-spring system is: F e x t = [ i n e r t i a ] y ″ + [ d a m p i n g ] y ′ + [ s t i f f n e s s ] y = m y ″ + b y ′ + k y Consider F e x t = 0 . In the case of underdamped, b 2 − 4 m k < 0 and there will be two complex conjugates to the associated auxiliary equation. For the roots α ± i β , the general solution that determines the motion will be y ( t ) = e α t ( C 1 cos β t + C 2 sin β t ) . The solution form can also be expressed as y ( t ) = A e α t sin ( β t + ϕ ) , where A = C 1 2 + C 2 2 and tan ϕ = C 1 C 2 . The constant A is called the amplitude, A e α t is the damping constant, ϕ is the phase angle, the quasiperiod is P = 2 π β and the quasifrequency is 1 P . Calculation: Given that, mass 1 4 kg is attached to a spring with stiffness 8 N/m and the damping constant is 1 4 N-sec/m . That is, m = 1 4 , k = 8 and b = 1 4 . Thus, the governing equation of a mass-spring system F e x t = m y ″ + b y ′ + k y for 0 external force becomes, 1 4 y ″ + 1 4 y ′ + 8 y = 0 . Multiply by 4 to obtain y ″ + y ′ + 32 y = 0 . The associated auxiliary equation is, r 2 + r + 32 = 0 . Factorize r 2 + r + 32 = 0 using quadratic formula − b ± b 2 − 4 a c 2 a as, r = − 1 ± ( 1 ) 2 − 4 ( 1 ) ( 32 ) 2 ( 1 ) = − 1 ± 1 − 128 2 = − 1 ± − 127 2 = − 1 ± 127 i 2 ( ∵ i = − 1 ) = − 0.5 ± 0.5 127 i That is, the roots are r 1 = − 0.5 + 0.5 127 i and r 2 = − 0.5 − 0.5 127 i . Here, α = − 0.5 and β = 0.5 127 . Thus, the solution form y ( t ) = e α t ( C 1 cos β t + C 2 sin β t ) becomes y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) . Given that, the mass is moved 1m to the left from the equilibrium and released. That is, y ( 0 ) = − 1 and y ′ ( 0 ) = 0 . The negative sign indicates the left direction. Apply the initial conditions to obtain the value of the constants as follows: Substitute t = 0 and y ( 0 ) = − 1 in y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) , y ( 0 ) = e − 0.5 × 0 ( C 1 cos ( 0.5 127 × 0 ) + C 2 sin ( 0.5 127 × 0 ) ) − 1 = C 1 cos ( 0 ) + C 2 sin ( 0 ) C 1 ( 1 ) + C 2 ( 0 ) = − 1 C 1 = − 1 Differentiate y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) with respect to t as, y ′ ( t ) = [ e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) ) − 0.5 e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) ] = [ e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) ) + e − 0.5 t ( − 0.5 C 1 cos ( 0.5 127 t ) − 0.5 C 2 sin ( 0.5 127 t ) ) ] Simplify as, y ′ ( t ) = e − 0.5 t ( − 0.5 127 C 1 sin ( 0.5 127 t ) + 0.5 127 C 2 cos ( 0.5 127 t ) − 0.5 C 1 cos ( 0.5 127 t ) − 0.5 C 2 sin ( 0.5 127 t ) ) = e − 0.5 t ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 t ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 t ) ) Substitute t = 0 and y ′ ( 0 ) = 0 in y ′ ( t ) = e − 0.5 t ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 t ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 t ) ) , y ′ ( 0 ) = e − 0.5 × 0 ( ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0.5 127 × 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0.5 127 × 0 ) ) 0 = ( − 0.5 127 C 1 − 0.5 C 2 ) sin ( 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) cos ( 0 ) 0 = ( − 0.5 127 C 1 − 0.5 C 2 ) ( 0 ) + ( 0.5 127 C 2 − 0.5 C 1 ) ( 1 ) 0.5 127 C 2 − 0.5 C 1 = 0 Since C 1 = − 1 , the above equation becomes, 0.5 127 C 2 − 0.5 ( − 1 ) = 0 0.5 127 C 2 = − 0.5 C 2 = − 0.5 0.5 127 C 2 = − 1 127 That is, C 1 = − 1 and C 2 = − 1 127 . Thus, the solution y ( t ) = e − 0.5 t ( C 1 cos ( 0.5 127 t ) + C 2 sin ( 0.5 127 t ) ) becomes, y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) . The aim is to find the which maximum displacement. Note that, the maximum displacement will be obtained at y ′ = 0 . Differentiate y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) with respect to t as, y ′ ( t ) = [ e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) − 0.5 127 127 cos ( 0.5 127 t ) ) − 0.5 e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) ] = [ e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) − 0.5 cos ( 0.5 127 t ) ) + e − 0.5 t ( 0.5 cos ( 0.5 127 t ) + 0.5 sin ( 0.5 127 t ) ) ] Simplify further as, y ′ ( t ) = e − 0.5 t ( 0.5 127 sin ( 0.5 127 t ) + 0.5 sin ( 0.5 127 t ) ) = 0.5 ( 127 + 1 ) e − 0.5 t sin ( 0.5 127 t ) Thus, y ′ = 0 implies, 0.5 ( 127 + 1 ) e − 0.5 t sin ( 0.5 127 t ) = 0 e − 0.5 t sin ( 0.5 127 t ) = 0 Note that, the value of the exponential is never zero. Thus, the only possibility is sin ( 0.5 127 t ) = 0 . This happenes only when 0.5 127 t = n π . Simplify further as, t = n π 0.5 127 . The first value is obtained when n = 1 . Thus, n = 1 implies t = π 0.5 127 . On simplification, t = 2 π 127 . That is, the maximum displacement occurs at t = 2 π 127 . Substitute t = 2 π 127 in y ( t ) = e − 0.5 t ( − cos ( 0.5 127 t ) − 1 127 sin ( 0.5 127 t ) ) , y ( 2 π 127 ) = e − 0.5 × 2 π 127 ( − cos ( 0.5 127 × 2 π 127 ) − 1 127 sin ( 0.5 127 × 2 π 127 ) ) = e − π 127 ( − cos ( π ) − 1 127 sin ( π ) ) = e − 0.2788 ( 1 − 1 127 ( 0 ) ) = 0.7567 ( 1 − 0 ) = 0.7567 That is, the maximum displacement is 0.7567m.
