Find the value s so that the worker can climb the ladder without causing it to slip. The weight of the worker is 90-kg and neglect the weight of the ladder. The ladder has a small roller at the top and at the ground the coefficient of static friction is 0.25. The center of mass of the worker is directly above her feet. B 4 m 1.5 m
The coefficient of static friction between the 65-lb roller and the ground is μ = 0.2. Fins the greatest force P that can be applied to the handle to that the roller rolls on the ground without slipping. The roller can be assumed to be a uniform cylinder. Note: when a wheel rolls without slipping, the point of contact between the wheel and the ground is stationary, so the static coefficient of friction is used. 40° 3 ft
The figure shows a part of a machine used to crush recycled cans. Link ABC is attached to the ground at pin A and link BD is attached to the piston D using also a pin connection. When α=45°, θ=55°, and β=15°, the machine is about to start moving, i.e. impending motion. If the coefficient of static friction and kinetic friction between the piston D and the wall are μs=0.25 and μk=0.2 respectively, find the magnitude of force applied to the cans by the piston for P=200 kN.
