Multiple forces act on an object at the same time. The size and direction of these forces determines the movement of the object. Show the forces acting on an object in a free body diagram. The arrows ...

Do you need some practice with force diagrams for your introductory (or advanced) physics course? Here are three questions (and the last one is awesome) about the motion of a bike as it is pulled.

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...

Pressure is a measure of how concentrated a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over. Force diagrams and resultant ...

The goal of mechanobiology is to develop a mechanical description of cells and their parts. Platelet clotting, for example, is an important biological process that can only be fully understood if a ...

THIS is a reprint in book-form, with additions, of a series of articles which appeared in Engineering in the autumn of 1906. Those who have had any experience of such work will know how tedious is the ...
