Two blocks A and B shown in (Figure 1) have a weight of 9 lb and 6 lb , respectively. They are resting on the incline for which the coefficients of static friction are μA = 0.13 and μB = 0.23. Determine the angle θ which will cause motion of one of the blocks. What is the friction force under each of the blocks when this occurs? The spring has a stiffness of k = 2 lb/ft and is originally unstretched

Question

Two blocks A and B shown in (Figure 1) have a weight of 9 lb and 6 lb , respectively. They are resting on the incline for which the coefficients of static friction are μA = 0.13 and μB = 0.23. Determine the angle θ which will cause motion of one of the blocks. What is the friction force under each of the blocks when this occurs? The spring has a stiffness of k = 2 lb/ft and is originally unstretched.

Part A

Determine the smallest angle θ which will cause motion of one of the blocks.
Express your answer in degrees to three significant figures.
 
 
 

Part B

Determine is the friction force under the block A at this angle.
Express your answer to three significant figures and include the appropriate units.
 
 
 

Part C

Determine is the friction force under the block B at this angle.
Express your answer to three significant figures and include the appropriate units.
