The crane truck has a weight of 11750 lb and a center of gravity at point CG. The parking brake only locks the rear wheels of the truck, so the front wheels are free to rotate. Determine the maximum force F applied at the angle = 32.5° that can be exerted on the crane without it slipping or tipping for each of the following cases: Case 1: The static friction coefficient between the rear tires and the ground is pe...

D | Question 2 1 pts A mass m slides up an incline (with 0 27.6 degrees above the horizontal) until it stops momentarily because of friction. The coefficient of static friction between the mass and incline is 0.7; the coefficient of kinetic friction between the mass and incline is 0.4. At a given instant, the mass is moving with speed of 7.1 m/s up the incline. How far beyond this point along the incline will the mass move before...

Question 1 2 pts The figure shows a climber of mass 68 kg held up by a rope connected to her climbing harness. The force of the rope has a line of action passing through her center of mass. The angle = 45 degrees and o = 28.9 degrees. If her feet are just about to slide on the vertical wall (i.e., the friction is at its maximum), what is the coefficient of static friction between her shoes and the...

Question 4 8 pts A box of mass m = 7 kg is being pushed up a ramp that is angled 15 degrees above horizontal. The pushing force P = 49 N. The coefficient of kinetic friction is 0.215. At a certain time the velocity of the box moving up the ramp is 1.0 m/s. How far will the box been pushed during the next 3.0 seconds assuming the same pushing force is applied? In your solution you must show:...
