Question
A string og negligible mass going over a clamped pully of mass m support a block of mass M as shown in the figure. The force on the pulley by the clamp is given by
Options
A.√2 Mg
B.√2 mg
C.
D.
Solution
Free body diagram of pulley is shown in figure. Pulley is in equilibrium under four forces. Three forces as shown as shown in figure and the fourth, which is equal and opposite to the resultant of these three forces, is the force force applied by the clamp on the pulley (say F) Resultant R of these forces is
R =
Therefore, the force F is equal and opposite to R as shown in figure.
∴ F =
