Question

The lever supports load of 100kg with force P applied equal to 20kg . calculate the distance between the load and the point of force. ​

Answer 1

Step-by-step explanation:

(a) A machine is a device by which we can either overcome a large resistive force at some point by applying a small force at a convenient point and in a desired direction or by which we can obtain a gain in the speed.

load =100kg

effort =20 kg

let effort arm= x cm

load arm= 50 kg

As per principals of levers:

17x =100× 50

x=( 100 × 50) /20 = 250

x= 250

distance between the load and the point of force:

250-50

= 50
