A 64 kg student stands on a very light, rigid board that rests on a bathroom scale at each end, as shown in Figure P8.1 . What is the reading on each of the scales?
Solution : In the above question, they have given A 64 kg student stands on a very light, rigid board that rests on a bathroom scale at each end, as shown in the above figure. We need to find the reading on each of the scales Step 1 Static equilibrium : Static equilibrium is a form of equilibrium that occurs when an object is at rest. “Static” refers to the object being motionless while “equilibrium” refers to the object either having no net forces acting upon it or having all of its net forces balanced. The above figure shows that the body will be in static equilibrium if the net force F= 0, The net torque acting on the body equal to zero as well as the body does not change its position with respect to time.
