Question

The simple 2-kg pendulum is released from rest in the horizontal position. As it reaches the bot- tom position, the cord wraps around the smooth fixed pin at B and continues in the smaller arc in the vertical plane. Calculate the magnitude of the force R supported by the pin at B when the pendu- lum passes the position = 30°.

Answer 1

The question relates to calculating the force on a pin by a swinging pendulum at a 30° angle, but it lacks sufficient details for a full solution. It involves principles of mechanical energy conservation and dynamics within the realm of physics.

Step-by-step explanation:

The student's question is regarding the force supported by a fixed pin when a pendulum wraps around it after being released from rest in a horizontal position and passes a certain position at an angle of 30°. To solve this problem, we must consider the conservation of mechanical energy and the forces acting on the pendulum at the given angle. However, there's insufficient data in the question provided to give a precise answer to the force exerted by the pin. This problem typically requires knowing the length of the pendulum, the mass of the bob, and the gravitational acceleration.
