A rectangular block of size 
is kept in three different positions P, Q and R in turn as shown in the figure. In each case, the shaded area is rigidly fixed and a definite force F is applied tangentially to the opposite face to deform the block. The displacement of the upper face will be
Text Solution
Verified by ExpertsThe correct answer is:
D
⇒ ⇒ 
If η η and F are constant then 
For maximum displacement area at which force applied should be minimum and vertical side should be maximum, this is given in the R position of rectangular block.
