A beam resting on two pivots has a length of L = 6.00 m and massM = 78.7 kg. The pivot under the left end exerts a normal force n1on the beam, and the second pivot placed a distance l = 4.00 m fromthe left end exerts a normal force n2. A woman of mass m = 58.2 kgsteps onto the left end of the beam and begins walking to theright. The goal is to find the woman's position when the beambegins to tip. Find the value of n2 when the beam is about totip.
