Answer to Problem 1OQ

Solution:

Option (a)FA is down, FB is up and FB is larger than FA.

Explanation of Solution

Torque can be understood as a force that tends to cause rotation.

τ=r×F=rFsinθ

Weight of the diver will act downwards. The reaction forces will act upwards at A and B.

Physics, Chapter 9, Problem 1OQ

τA=0FB(xAxB)=MgxAFB=MgxA(xAxB)...(1)τB=0FA(xAxB)=MgxBFA=MgxB(xAxB)...(2)xA>xBFB>FA
