...In the CGS system this quantity is called an erg (from epyov, work). Since work is proportional to the product of the force acting and the distance through which it acts, we may write as the equation of work w =^fi Evidently if f and I be both unity, iv will also...

...tonds to separate the molecules from one another. Eneri/ij of a body is its capacity of doing work, and is measured by the product of the force acting and the distance through which it acts. Crystals are solid substances bounded by plane surfaces symmetrically arranged according to fixed...

...enough to balance (or not quite equal) the torque in the direction of the arrow. Now, since work is the product of the force acting, and the distance through which it acts, the brake horsepower will be expressed by the formula 2 BHP = rnw in which 33,000 r — the radius...

...increase or decrease? Why? ENERGY AND EFFICIENCY Theory In the preceding experiment work was denned as the product of the force acting and the distance through which it moves the point to which it is applied. Symbolically, w=Fs. The energy of an agent is denned as its capacity...

...decrease? Why? •" V ENEEGY AND EFFICIENCY Theory In the preceding experiment ^vork was defined as the product of the force acting and the distance through which it m oves the point to which it is applied. Symbolically, W=Fs. The energy of an agent is defined as its...

...Poisson's ratio equals -r— " • 2 m + 1 5 4 19. Work Done in Deforming a Body. Resilience. Since work is measured by the product of the force acting and the distance through which it acts, the work done in elongating a steel bar, for example, is equal to the elongating force times...

...metal into glass. CHAPTER VIII WORK AND MECHANICAL ENERGYi DEFINITION AND MEASUREMENT OF WORK 202. Definition of work. Whenever a force moves a body...distance through which it moves the body. Thus if 1 g. of mass is lifted 1 cm. in a vertical direction, 1 g. of force has acted, and the distance through...

...in carrying the unit pole through the interior of the solenoid is Hl ergs, since (p. 81) work equals the product of the force acting and the distance through which it acts. We must now remember that all the lines of force due to the current pass through the interior...

...its length? \ \ '. V" \,CHAPTER VI WORK AND ENERGY 104. Work. — "Whenever a force moves a body upon which it acts, it is said to do work upon that body." For example, if a man pushes a wheelbarrow along a path, he is doing work as long as the wheelbarrow...

...When a force acts against resistance to produce motion in a body the force is said to do work. Work is measured by the product of the force acting and the distance moved through against the resistance. Units of Work. — The erg, a force of one dyne acting through...
