Asmall ice flakewith a mass of 0.1 kg is released from rest at point a. when it reaches point bat the bottom of the hemispherical bowl the ice flakeis observed to have a speed of 1.8 m/s. calculate the work done by friction on the ice flakewhen it moves from ato b.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Blank liquids and gases exert a buoyant force on objects placed in them
