Q. A beam resting on two pivots has a length of L = 6.00 m and mass M = 92.0 kg. The pivot under the left end exerts a normal force n1 on the beam, and the second pivot placed a distance script i = 4.00 m from the left end exerts a normal force n2. A woman of mass m = 57.5 kg steps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip.

a- where will the women be when the normal force N1 is the greatest?

b- What is n1 when the beam is about to tip?

c. use the force equation of equilibrium with torques to compute around the second pivot pt, fine the women's position when the beam is about to tip

d -using info in part b- and the torque equilibrium equation with torques computed around the second pivot point, find the womens position when beam is about to tip

e. Check answer to part (d) by computing torques around first pivot pot
