Question

A lever of 1.8m has a load of 40kgf at a distance of 20cm from one end and fulcrum is at the end of a shorter arm. The effort is applied at the end of a longer arm. Find 1) Length of the load arm 2) Mechanical Advantage 3) The effort required. pls tell me the answer fast. very urgent. I will mark him or her brainliest...pls pls

Answer 1

length of load arm will be 20cm or 0.2m

mechanical advantage =effort arm ÷load arm

=1.6÷0.2=8

but M.A=load ÷effort

8=40÷E

8E=40

E=5
