A rectangular block of size 
is kept in three different positions 
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:
C
If 
and F are constants, then 
.
For maximum displacement, area at which force applied should be minimum and vertical side of the block should be maximum. This condition is satisfied when the block is kept in position Q.
