12.To undergo small motions that result in friction and wear:The gears work against each other. v.tr. 1.To cause or effect; bring about:working miracles. 2.To cause to operate or function; actuate, use, or manage:worked the controls; can work a lathe. ...
force acting on a moving body is constant in magnitude and direction, the amount of work done is defined as the product of just two factors: the component of the force in the direction of motion, and the distance moved by the point of application of the force. Thus the defining equation...

component in the direction of displacement, then the work done by the force is positive. hence, when a body falls freely under the influence of gravity the work done by the gravity is positive. q3 when a body slides against a rough surface, the work done by friction is positive or ...

aIn the light of the assumptions, this equation is simplified by omitting the potential-energy terms, noting that Cl.u = Cl.b = 1.0, u = V, and restricting the friction to wall shear. Equation (6.5) then becomes 根据假定,这个等式通过省去潜力能量期限,注意那Cl.u = Cl.b = 1.0, u =...
