A particle of mass 5kg is held at rests on a slope inclined at 30 degrees to the horizontal. The coefficient of friction for the slope is 0.7, determine whether the particle will move when released.

Frictional force acting: F Max = u R = 0.7 x 5 x 9.81 x cos(30) F Max = 29.7N Weight acting down the slope: F = 5 x 9.81 x sin(30)F = 24.5N Frictional max is greater than the weight acting down the slope, th...
