A bead of mass m can slide on a smooth circular wire of radius a, which is fixed in a vertical plane. The bead is connected to the highest point of the wire by a light spring of natural length 3a/2 and strength λ.
Determine the stability of the equilibrium position at the lowest point of the wire in the cases (i) α = 2mg/a, and (ii) λ = 5mga.
where k is the coefficient of kinetic friction between the blocks and the ground. Also, what is the distance the blocks slide on the surface before they separate?
The crate shown is held against wedge B by a spring. The spring is 94.5% of its original uncompressed length l=2.75m, and the spring constant is given as k=1650N/m. The coefficient of static friction at all contacting surfaces is ?s=0.130. The mass o..
