Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

Consider the pulley system depicted in the figure. The block is prevented from moving by the applied force F. Assume the pulleys are massless and frictionless. An illustration shows a rectangular block of mass M suspended from a horizontal surface by a complex pulley system comprised of one large pulley, one small pulley, two short ropes, and one long rope. The pulleys are drawn such that the small pulley is some vertical distance below the large pulley and their axles are perpendicular to the page. The left side of the small pulley aligns vertically with the center of the large pulley. One of the short ropes suspends the block of mass M from the bottom of the small pulley's harness and has tension T5. The remaining short rope and the long rope are, respectively, anchored to the top and bottom of the large pulley's harness. This short rope has tension T4 and suspends the large pulley from the horizontal surface. The long rope extends from the large pulley and cradles the small…

Learning Goal: To replace force-couple systems with an equivalent force by specifying the magnitude and direction of the equivalent force and the location where the force needs to be applied. Certain force-couple systems can be replaced by a single force. The requirement is that the lines of action of the resultant force, FR, and the resultant couple moment, (MR)o, are perpendicular to each other. This is equivalent to saying the following types of force systems can be simplified to a single force: Figure F₂ X F₁ 3 ft A B 2 ft < 2 of 3 C
