Question

What load can be lifted by an effort of 800N if the effort arm is 80cm and the load arm is 20cm?​

Answer 1

load (l) =?

LOAD ARM = 20 CM

EFFORT ( E)= 800N

EFFORT ARM = 80cm

load *load arm = effort *effort arm

l*20 cm = 800 *80

L = 64000/20

answer = 3200

Answer 2

Explanation:

Solution,

Effort=800N

Effort arm=80 cm

Load arm=20 cm

Load=?

Now,

by the principle of lever, we have

• Load×Load arm=Effot×Effort arm
• Load×20=800×80
• Load=800×80/20
• Load=3200 N

So, the load of 3200N can be lifted .
