Answer:
A metal cube of side 10cm is subjected to a shearing stress of 104Nm−2. The modulus of rigidity if the top of the cube is displaced by 0.05cm with respect ...
Top answer
We know that shearing stress = FA = 104Nm-2 Length of side of cube = 10cm = 10100 m = 0.1m Shearing displacement = n = 0.05cm = 0.05100 m = 0.0005m We know ... More.... and please follow me please please please

Answer:
It's a 12Nm-2
Explanation:
=Length:3m
=Normal Force:36N
=Stress=??
=Let, Assume Stress as A
=A=Length ÷ Normal Force
=A=3 ÷ 36
=A=12Nm
=Hence Option A 12Nm-2 is the right Answer
