...there will be an equilibrium if the power Is equal to half the weight only. 89. In the inclined plane there will be an equilibrium when the power Is to the weight as the height of the plane Is to the length. 40. In the wedge, the power will be to the weight as half the...

...other, find the tension of! each string. 8. Thero is equilibrium on the wheel and axle, when the i power is to the weight as the radius of the axle is to the radios j of the wheel. 9. Define the centre of gravity of a body ; and shew that I every body has one...

...represented in magnitude and direction by the sides of a triangle, act on a point, they will keep it at rest. when the power is to the weight as the radius of the axle to the radius of the wheel. 23. Define the centre of gravity, and find it in the case of a triangle....

...or P : R nr : p. That is, in the equilibrium of the wheel and axle, the power is to the resistance as the radius of the axle is to the radius of the wheel. When P and R act upon the machine by means of cords, we must suppose these forces applied to the axes...

...arm of the lever, and the radius of the axle AB the short arm ; consequently (108) the power must be to the weight as the radius of the axle is to the radius of the wheel. If we suppose the wheel to be turned once round, it is plain that the power will fall a distance just...

...follows : — There will be Equilibrium in the wheel and axle, when the Power is to the Resistance as the radius of the axle is to the radius of the wheel. One of the most common examples of the wheel and axle is the windlass, in which the Power is applied...

...P : R :: r : p. That is, in the equilibrium of the wheel and axle, the potver is to the resistance as the radius of the axle is to the radius of the wheel. When P and R act upon the machine by means of cords, we must suppose these forces applied to the axes...

...the force which will keep the point at rest ? 3. Describe the Wheel and Axle; and prove that there is equilibrium when the power is to the weight as the radius of the axle to the radius of the wheel. 4. In a system of pullies in which the same string passes round all the...

...the forces when the pressure on the fulcrum is 31bs. 6. There is equilibrium on the wheel and axle when the power is to the weight as the radius of the axle to the radius of the wheel. What is meant by the mechanical advantage of a machine ? How may this be...

...means of a rope, and the weight to the axle, on the opposite side. •524. An equilibrium is produced when the power is to the weight as the radius of the axle to the radius of the wheel. The principle is the same as in the lever, the radius of the axle corresponding...
