Transcribed Image Text:### Problem Description
The diagram shows a configuration with three blocks, labeled A, B, and C, connected by cords over pulleys. The blocks are positioned on inclined planes with the following details:
- **Block A**:
- Weight (WA): 4 lb
- Positioned on an incline at 25°
- Coefficient of kinetic friction (µk): 0.15
- **Block B**:
- Weight (WB): 6 lb
- Positioned horizontally
- **Block C**:
- Weight (WC): 8 lb
- Positioned on an incline at 55°
- No friction on the incline for block C
### Problem Statement
For the configuration of blocks and cords shown above, determine the following:
(a) \( a_c \) (magnitude and direction of acceleration)
(b) \( T_1 \) (the tension in the cord joining blocks A and B)
(c) \( T_2 \) (the tension in the cord joining blocks B and C)
### Diagram Explanation
- Block A is shown on a 25° inclined plane with a friction coefficient of 0.15.
- Block B is positioned on a flat surface between the two inclined planes.
- Block C is shown on a 55° inclined plane with no friction.
- Cords pass over pulleys connecting the blocks, with tensions \( T_1 \) and \( T_2 \) in the cords as shown.
### Objective
Calculate the acceleration of block C, and the tensions in the cords that connect the blocks for the given system.
