Answer 1

Answer:

Answer is 540N

Explanation:

Effort arm=40cm

Load arm =60cm

Load=360N

effort=?

Now,

According to formula,

           Input work = Output work

or, Effort*Effort arm = Load*Load arm

or, Effort*40 = 360*60

or, Effort * 40 = 21,600

or, Effort = 21,600/40

or, Effort = 540

                                 Therefore, The Effort that Reha should apply to lift                        

                                                     Neha should apply is 540n
