Στ = 0
Take counterclockwise torque as positive.
Consider a rigid steel beam of length L = 14.5 m and mass m = 380 kg resting on two supports, one at each end. A worker of mass m, = 62 kg sits on the beam at a distance x from support A. Refer to the figure
When the worker sits at a distance x = 2.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it to remain at rest. Use g with three significant figures
