A steel rod 15m long is at a temperature 15°c. Find the free expansion of the length when the temperature is raised to 65°c. Find the temperature stress produced when
1. The expansion of the rod is prevented
2. The rod is permitted to expand by 6mm.
Take: Elastic modulus = 200GN/m^2 and temperature coefficient = 12 × 10^-6°c

A hollow cast iron cylinder, 4m long 30mm outer diameter and the thickness of 50mm. Is subjected to a central load on the top when standing straight. The stress produced is 750KN/m^2, assume Young's modulus of cast iron = 1.5×10^8KN/m. Find
1. Magnitude of the load
2. Longitudinal strain produced
3. The total decrease in length

A straight bar of uniform cross section is subject to an axial tension, the cross sectional area of the bar is 50mm^2 and it's length is 2mm under a load of 40kN. Find the modulus of elasticity

A straight aluminum wire 30m Long is subject to a tensile stress of 70MPa.
1. Determine the total elongation of the wire.
2. What temperature change would produce the same elongation
Take: Elastic modulus = 200GNM^-2 And temperature coefficient = 25 × 10^-6

How do you calculate the 2nd area movement (Iy,Iz) for a segment of a circle with a freely chosen angle? (z-axis is a symmetry axis)

A body of weight W = 120N is pushed by a horizontal for P = t2 + 6. A frictional force f= t3- 5 resists
its motion. If the body starts from rest, find the velocity of the body after 3 seconds.
