Question

A meterstick weighing 1.2 N is supported horizontally by two fulcra positioned at x1 = 30 cm and x2 = 90 cm. Assume that the stick's center of gravity is at its exact center (i.e., xcg = 50 cm). Draw a diagram of the three forces acting on the meterstick. What are the magnitudes of the upward forces exerted by the two fulcra on the stick?

Answer 1

Use the vertical equilibrium of the meter stick and rotational equilibrium to find the required magnitude of the force exerted by the two fulcra on the stick as shown below
