A diver stands at rest at the end of a massless diving board asshown.
(a) If the mass of the diver is 78 kg and the board is 4.5 m long,what is the magnitude of the torque due to gravity on the divingboard with a pivot point at the fixed end of the board?
1 N · m
(b) According to our convention for positive and negative torques,is the torque on the diving board positive or negative?
2
Positive Negative
