Question

a pair of scissors has its blades 15 cm long it's handle are 7.5 cm long what is this mechanical advantage

Answer 1

Effort Arm = 7.5
Load Arm = 15
M.A = Effort arm / Load Arm
= 7.5 / 15
= 1/2
= 0.5

Therefore Mechanical Advantage of the scissors is 0.5
 

Answer 2

M.A = Effort arm / Load Arm

       = 7.5 / 15  

       = 1/2  

       = 0.5

Therefore Mechanical Advantage of the scissors is 0.5
