A beam resting on two pivots has a length of L = 9.00 m and mass M =89.0 kg. The pivot under the left end exerts a normal force n1 on the beam, and the second pivot placed a distance 4.00 m from the left end exerts a normal force n2. A woman of mass m= 48.0 kg steps onto the left end of the beam and begins walking to the right as in the figure. The goal is to find the woman’s position when the beam begins to tip. (d) Use the torque equilibrium equation, with torques computed around the second pivot point and find the woman’s position when the beam is about to tip
