The brake mechanism used to reduce recoil on certain types of barrels essentially consists of a piston attached to a barrel that moves in a fixed cylinder. full of oil. When the barrel recoils with an initial velocity Vo, the plunger moves and oil is forced through the holes in the plunger, causing the piston and the barrel to slow down at a rate proportional to their velocity; that is, a = - ku. Express a) U in terms of r, b) x in terms of r, c) U in terms of x. d) Draw the curves of the corresponding movement

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
