A Bulldozer Attempts to Drag a Log Weighing 500 N

question 95

Short Answer

A bulldozer attempts to drag a log weighing 500 N along the rough horizontal ground.The cable attached to the log makes an angle of 30° above the ground.The coefficient of static friction between the log and the ground is 0.50,and the coefficient of kinetic friction is 0.35.What minimum force should the cable exert on the log tension in order for the log to begin to slide?
