Calculating the force acting on a pulley in a hoist system In the diagram below there is a hoisting system set up to lift a 1000 lb. unit up a radio tower. This unit is used for painting towers and is lifted using a capstan hoist. As the unit is lifted, it will be tagged with a...
Homework Statement Givens: Mass of Cart = 1156g = 1.156kg Mass on string = 400g = 0.4kg Mass on Cart = 1003g = 1.003kg The weight attached to the pulley generates the applied force. Homework Equations Calculate the force applied. The Attempt at a Solution Look on the sheet. ...

This weight, fastened to a string, which is wound round a pulley connected with the first toothed wheel of the clock, cannot obey the pull of gravity without setting the whole clockwork in motion. Now I must beg you to pay special attention to the following points: the weight cannot put ...
(14 lbs.). I raise a to the pulley; I allow it to fall. You observe that b, though double the weight of a, is again chucked up after the rope has become tight. We can only explain this by the supposition that the tension in the rope exerted in checking the motion of a is at...
The pulley has a ring-shaped rotational guiding element (2) with an external surface (S1) forming a groove guiding a cordage, and rotationally mounted on an annular support structure (ST), which includes fixation units for fixing another cordage. Detectors (12-15) i.e. strain gauges, are ...
In the situation below, what is the tension in string 1? a. 69.3 N b. 98 N c. 138.6 N d. 147.6 N e. 1.55 N 45125 kg2. Two masses, M and m, are hung over a massless, frictionless pulley as shown below. If M > m, what is the downward acceleration of mass M? 2、a. g...
It means the force exerted by the human body when in direct contact with the ground. Also, the ground too exerts an equal and opposite amount of force, keeping the body at rest. Example: Standing/Sitting – on the ground. 2.Joint Reactions ...
Where W is the weight of the paper and F is the force exerted by the rod on the paper. We can solve for F by rearranging the equation: F = (60 N + W)/μ Substituting in the values, we get: F = (60 N + 156.8 N)/0.25 = 646.8 N Therefore, the magnitude of the force that...
