plane p _ W v/ £ 2 i length of plane Example. What force is necessary to keep a weightof 100 pounds stationary on an inclined plane whose per-pendicular height is 4 feet and length of incline 14 feet,supposing there is no friction? Thus P = i^-4 = 4™ 28f lb.14 14 p = Power or force. Example. The… … Fig. 98 ThusP = 250 X 6 1500 19 19 78.9 lb. Ans. To find the weight: Multiply the power by the lengthof the plane and divide by the height. W = PX LH W = WeightP = Power L = Length of planeH = Height Example. The length of an inclined plane is 15 feet,the perpendicular height 7 feet. What weight…
