Suppose that a particular machine in a factory has two steel pieces that must rub against each other at a constant speed. Before either piece of steel has been treated to reduce friction, the force necessary to get them to perform properly is 5.8 N. After the pieces have been treated with oil, what will be the required force? NOTE: Use the Chart on the HANDOUT for the values of Mk.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

to reduce friction, the force necessary to get
them to perform properly is 5.8 N. After the
pieces have been treated with oil, what will
be the required force?

Draw the shear diagram for the beam. Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note 1 - Make sure you place only one vertical line at places that require a vertical line. If you inadvertently place two vertical lines at the same place, it will appear correct visually because the lines overlap, but the system will mark it wrong. Note 2 - Indicate the segments for all values of x shown in the diagram. Even if a segment is a constant value 0, it should be drawn in the diagram. +0 No elements selected M V, lb 600- 500 400- 300- 200 100 0. -100 -200 -300- -400 -500- -600 50 lb/ft 20 ft 10 B 8 200 lb-ft 10 ft 30 x, ft ?
