To determine The magnitude of acceleration of point A at the instant by scalar-geometric method. Explanation Draw the acceleration diagram of the system as shown in Figure (1). Calculate the distance between the points A and C . A C ¯ = ( A D ¯ ) 2 + ( D C ¯ ) 2 (I) Here, distance between the points A and C is A C ¯ , distance between the points A and D is A D ¯ and distance between the points D and C is D C ¯ . Write the expression for the normal component of acceleration of point A with respect to point C . ( a A / C ) n = ( A C ¯ ) ω 2 (II) Here, normal component of acceleration of point A with respect to point C is ( a A / C ) n and angular velocity of the plate is ω . Write the expression for the tangential component of acceleration of point A with respect to point C . ( a A / C ) t = ( A C ¯ ) α (III) Here, tangential component of acceleration of point A with respect to point C is ( a A / C ) t and angular acceleration of the plate is α . Write the expression for the magnitude of acceleration of point A at that instant. a A = ( a C + 3 5 ( a A / C ) n − 4 5 ( a A / C ) t ) 2 + ( 4 5 ( a A / C ) n + 3 5 ( a A / C ) t ) 2 (IV) Here, acceleration of point A is a A and acceleration of point C is a C . Conclusion: Substitute 300 mm for A D ¯ and 400 mm for D C ¯ in Equation (I). A C ¯ = ( 300 mm ) 2 + ( 400 mm ) 2 = 500 mm = 500 mm ( 1 m 1000 mm ) = 0 To determine The magnitude of acceleration of point A at the instant by vector - algebraic method.

A viscoelastic column is made of a material with a creep compliance of D(t)= 0.75+0.5log10t+0.18(log10t)^2 GPA^-1 for t in s. If a constant compressive stress of σ0 = –100 MPa is applied at t = 0, how long will it take (= t1/2) for the height of the column to decrease to ½ its original value? Note: You will obtain multiple answers for this problem! One makes sense physically and one does not.

A group of 23 power transistors, dissipating 2 W each, are to be cooled by attaching them to a black-anodized square aluminum plate and mounting the plate on the wall of a room at 30°C. The emissivity of the transistor and the plate surfaces is 0.9. Assuming the heat transfer from the back side of the plate to be negligible and the temperature of the surrounding surfaces to be the same as the air temperature of the room, determine the length of the square plate if the average surface temperature of the plate is not to exceed 50°C. Start the iteration process with an initial guess of the size of the plate as 43 cm. The properties of air at 1 atm and the film temperature of (Ts + T)/2 = (50 + 30)/2 = 40°C are k = 0.02662 W/m·°C, ν = 1.702 × 10–5 m2 /s, Pr = 0.7255, and β = 0.003195 K–1. Multiple Choice 0.473 m 0.284 m 0.513 m 0.671 m

A 40-cm-diameter, 127-cm-high cylindrical hot water tank is located in the bathroom of a house maintained at 20°C. The surface temperature of the tank is measured to be 44°C and its emissivity is 0.4. Taking the surrounding surface temperature to be also 20°C, determine the rate of heat loss from all surfaces of the tank by natural convection and radiation. The properties of air at 32°C are k=0.02603 W/m-K, v=1.627 x 10-5 m²/s, Pr = 0.7276, and ẞ = 0.003279 K-1 The rate of heat loss from all surfaces of the tank by natural convection is The rate of heat loss from all surfaces of the tank by radiation is W.
