Example 3.3 A 125 kg concrete block A is pulling a 200 kg log from its resting position on a road surface with a 30 incline, as shown in the figure. If the coefficient of kinetic friction between the log and the incline is 0.5. 1. (a) In Example 3.3. explain the method to determine whether Block A will move upward or downward. (b) In this example, find the range of the static friction coefficient (.) that will keep Block A stationary.
