has a value of 0.36397, and the normal force is 60kN.

To determine the minimum required coefficient of friction , between the wall and spool such that the spool does not slip, which of the following statements are true? (Select all that apply.) 0.6 m- 000 60° 0.3 m Frictional force at A acts upward Frictional force at A acts downward Frictional force at A is equal top, NA Frictional force at A is greater than , NA Frictional force at A is less than , NA Normal force at A acts to the left Normal force at A acts to the right

Determine the horizontal force P required to cause slippage to occur. The friction coefficients for the three pairs of mating surfaces are indicated. The top block is free to move vertically. Assume m₁ = 106 kg, m₂ = 52 kg, m3 = 33 kg, µ₁ P Answer: P = m₂ m₂ M 3 μ₁₂ -H₂ -H3 N = 0.62, M₂ = 0.42, μ3 = 0.30.

(ii) The block on the left incline is 6kg. Find the mass of the block on the right incline so that the system is in equilibrium (no acceleration). All surfaces are frictionless.
