A horizontal bar has mass 5 kg , length 0.30 m and has a mass M at one end as shown in the accompanying schematic sketch. A cable is attached at point A, 0.05 ~m from the pivot point (fulcrum) P and its other end makes a negligible angle with the a rod joined to the pivot P . The top end of the rod is fixed to the roof. The maximum tension the cable can withstand is 1050 N . Then

Options

  1. Athe maximum value of M is 15 kg .
  2. Bthis design has the maximum mechanical advantage.
  3. Cthe maximum value of the horizontal component of the force at the pivot is 1050 N .
  4. Dthe maximum value of the normal component of the force at the pivot is 850 N .

Correct answer

D. the maximum value of the normal component of the force at the pivot is 850 N .
