Consider the diagram in Figure III where 30.581kg crate at A is connected to 20.387kg box at B by a frictionless pulley. If Ɵ= 40° and the coefficient of friction at all contact surfaces is 0.20, (A) Determine the minimum P applied on Box B directed to right with an inclination of 15° from horizontal should be required to prevent the crate and box from sliding. (B) Minimum magnitude of P applied on Box B directed to right with an inclination of 15° from horizontal enough to cause the crate and box to impend its motion to the right.

3. Consider the diagram in Figure III where 30.581kg crate at A is connected to  20.387kg box at B by a frictionless pulley. If Ɵ= 40° and the coefficient of friction at  all contact surfaces is 0.20, (A) Determine the minimum P applied on Box B directed  to right with an inclination of 15° from horizontal should be required to prevent the  crate and box from sliding. (B) Minimum magnitude of P applied on Box B directed to  right with an inclination of 15° from horizontal enough to cause the crate and box to impend its motion to the right.
