Question

a machine can open a nut by applying force of 150 N while using a lever handle of length 40cm .How long should the handle of machine be if he wants to open it by applying a force of only 50 N?​

Answer 1

hi mate here is ur answer

=======

Answer:

length of handle if he is able to open it by applying a force of 60N is 1m.

Explanation:

let forces=f1,f2, lenght=l1,l2 respectively.

f1×l1=f2×l2

150×0.4=60×l2

l2=1m

========

hope it is helpfull

Answer 2

Answer:

the handle of machine should be of length 1.2 m

Explanation:

moment of force when F=150N and length of handle=40 cm =0.4 m

Moment of force=150×0.4

                          =60 Nm

Required length of handle when force =50 n

Moment of force=F×d

 60 N= 50 N×d

d=60/50 m

=1.2 m
