Question

The blade of a pair of scissors are 2cm long,while its handles are 10cm long.Find it's mechanical advantage.​

Answer 1

Answer:

0.2 is the M.A.

Explanation:

We have,

=> Effort arm = 2 cm

=> Load arm = 10 cm

To find,

> Mechanical advantage

Solution,

=> M.A = Effort arm/Load arm

>> M.A = 2/10

>> M.A = 1/5

∴ M.A = 0.2

Answer 2

2

Explanation:

mechanical advantages is ratio of load lifted to effort applied to it

M.A. = load/ effort

OR

M.A. = effort arm/ load arm

here effort arm( handles of scissors )is equals to 10cm

and load Arm (Blades of scissors) is equals to 2 cm

M.A. = 10/5

=2
