4. Consider the RL circuit with a sinusoid voltage source shown in the diagram below. The values
of the resistor, inductor, input voltage amplitude and frequency are R = 5, L = 50mH,
and Vo = 10 V, respectively. The input voltage frequency w is variable. Assume that the
circuit has reached steady state.

The input voltage can be described using the complex sinusoid function
V(t) = Voejwt
The current is given by a sinusoid with same the frequency was the input voltage, but a
different magnitude and different phase. The physical voltage and current are obtained by
taking the real part. In complex form, the current is given by

The differential equation that describes the current follows from Kirchoff's voltage law, and
is given by

2. (4 marks) Use the real and imaginary parts of ĉejut, where ñ = a + jb = e³, to show that:
c cos(wt) = acos(wt) – bsin(wt),
csin(wt) = a sin(wt) + bcos(wt).

PROBLEM 1.33
A steel pipe of 300 mm outer diameter is fabricated from 6 mm thick
plate by welding along a helix which forms an angle of 25° with a plane
perpendicular to the axis of the pipe. Knowing that the maximum
allowable normal and shearing stresses in directions respectively
normal and tangential to the weld are σ = 50 MPa and 7 = 30 MPa,
determine the magnitude P of the largest axial force that can be applied
to the pipe.
