1)THE LENGTH OF THE LOAD ARM OF A LEVER IS 6m LONG AND THE EFFORT ARM IS 3m LONG. WHAT IS THE EFFORT REQUIRED TO LIFT A LOAD OF 40 N

2)THE LENGTH OF A LEVER IS 2m. CALCULATE ITS MECHANICAL ADVANTAGE IF THE FULCRUM IS SITUATED AT A DISTANCE OF 40cm FROM THE EFFORT.
PL. ANSWER FAST AND DONT WRITE UNNECESSARY OR I WILL REPORT. ITS A WARNING, REMEMBER THIS.

Answer 1

Answer:

1. answer...

Length of the Load arm=6m

Length of the Effort arm=3m

Force created by the Load=40N

If,

Mechanical Advantage - Load/Effort=Load Arm/Effort Arm

Then,

Effort=40N/x=3m/6m

or,x*3=40*6

or,x=40*6/3

or,x=80N
