Question
A steel ball starts rolling from rest down a steel plate inclined at 45° to the horizontal, as shown below.The plate is covered by a thin oil film of viscosity n. = 50 [cP] and pressure viscosity coefficient a = 2.2x10° [m²/N]. The diameter of the ball is d = 3x10² [m], Young's modulus is E = 2.1x10" [Pa], Poisson's r
