Homework Statement A man is pulling a 40.0 kg crate across a level floor with a horizontal force, and the coefficient of kinetic friction is μk = 0.59...
A proposition to reduce arithmetic to the dominion of mechanism,—to substitute an automaton for a compositor,—to throw the powers of thought into wheel-work could not fail to awaken the attention of the world. To bring the practicability of such a project within the compass of popular ...
Neglect any friction acting on the piano. Calculate the magnitude of the force applied by the man if he pushes parallel to the floor. Homework Equations I was able to calc the mag of force parallel to the incline using F=M*g*sin(theta). I don't know if this is useful... The ...
It will appear that the springs 19, in moving down the unlocking slide I1 and operating, through the mechanisms described, the cross totalizer and column totalizer unlocking levers and 32, must overcome the friction of the mechanism which, in addition to the gradual decrease in their tension, ...
