Question

If a 500 kg load is to be lifted with a 100N effort using a first class lever at what distance from the fulcrum must the effort be aaplied when the load is 20cm away from the fulcrum​

Answer 1

Explanation:

Hey there!

According to the question;

Load (l) = 500 kg

Effort (e) = 100 N

Load distance (ld) = 20cm

Effort distance (ed) = ?

According to the principal of lever;

L*LD = E*ED

500*20 = 100*ED

ED = (500*20)/100

Therefore, the Effort must be applied at 100 cm.

Hope it helps!
