Belt and Pulley System Analysis

What are the tensions in the belt portions B and C when the system is at rest?

Tension in belt portion B: 104 N

Tension in belt portion C: 164 N

What are the reactions at points A and D in the belt and pulley system?

Reactions at A and D:

When analyzing the belt and pulley system with two transmission belts passing over a double-sheaved pulley, it is crucial to consider the tensions in the belt portions B and C when the system is at rest. The given data provides the tension values of 104 N in both portions of belt B and 164 N in both portions of belt C.

By applying the principles of static equilibrium, we can determine the reactions at points A and D in the system. The reactions at points A and D represent the forces exerted on the axle supported by bearings at these points. These reactions are essential for understanding the overall stability and balance of the system.

To calculate the reactions at points A and D, we need to consider the forces acting on the system, including the tensions in the belt portions B and C and the radii of the inner and outer sheaves of the pulley. By applying the equations of static equilibrium, we can solve for the reactions at points A and D and ensure that the system is in a state of balance.
