# Torque experienced by a body under shearing stress

Given below is a piece of information from table 9.4 on page 243 from my standard NCERT class 11th textbook:

Two equal and opposite forces parallel to opposite surfaces forces in each case such that the total force and total torque on the body vanishes

And this information corresponds to shearing stress...I understand that net force will be zero but how is net torque zero?

I tried using right hand rule to get torque due to both forces in same direction (hence non zero torque), perhaps I'm doing it wrong...
