Forces and motion: A simple introduction

 · Forces and movement When a force acts on an object, it often makes it move faster or in a different direction. Once something is moving, you don''t need a force to keep it moving: it will carry on moving all by itself unless another force stops it. When a rocket blasts into space, you need a force to make it lift off to begin with and to overcome the force of Earth''s gravity.

Jaw Crushers

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher''s two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers.

Masticatory force

The jaw elevator muscles develop the main forces used in mastication. The force generated during routine mastication of food such as carrots or meat is about 70 to 150 newtons (16 to 34 lbf ). The maximum masticatory force in some people may reach up to 500 to 700 newtons (110 to 160 lbf ).

Grade 7-9 Workbooks

Car Crash

 · How to calculate impact force? G-force in car crashes Impact force formulas we used above describe an ideal collision between two objects. In the real situation of a car crash, the profile of force during the accident can be more extensive - e.g., you should take into account that car collapses and that a human is not a point mass but a complex body.

Cone Crusher Parts

 · Cone Crusher MAINSHAFT. The mainshaft is of high grade forged steel, annealed for stress relief. It is tapered to gauge for head center fit. The bottom of the shaft is fitted with a polished bronze step bearing. The journal for the spider bearing is formed by a sleeve shrunk on the shaft on the 51, 60 and 84-in. crushers.

Forces and Torques in Muscles and Joints | Physics

Because muscles can contract, but not expand beyond their resting length, joints and muscles often exert forces that act in opposite directions and thus subtract. (In the above example, the upward force of the muscle minus the downward force of the joint equals the weight supported—that is, 470 N–407 N = 63 N, approximately equal to the weight supported.)
