Question 6
A circular shaft fixed at A has diameter d for half of its length and diameter d/2 over the other half what is the rotation of C relative to B if the rotation of B relative to A is 0.1 radian?
Question 7
A frame is subjected to a load P as shown in the figure. The frame has a constant flexural rigidity EI. The effect of axial load is neglected. The vertical deflection at point A due to the applied load P is
Question 8
A cantilever AB of length ‘L’ has fixed end A and free end B. It is loaded by applying a concentrated load W at the mid point C of the cantilever.
