Question

01) When operating a simple machine an effort of 60N is used to lift the load of 240 N. Find the mechanical advantage.

02) When operating the same machine the effort arm moves 4m while load moves 1m. Find velocity ratio

03) In the same machine find work input.

04) In the same machine find work output.

05) Find the efficiency of this simple machine.

Answer 1

1 MA= load/effort

MA= 240/60

MA=4

2.VR=Distance moved by effort/ Distance moved by Load

VR=4/1

= 4

5. Efficiency= MA/VR

4/4*100/1

=100%
