Question

What is the relationship between the mechanical advantage and the velocity ratio for:

1) An ideal machine; 2) A practical machine?

• A. 1) M.A < V.R 2) M.A < V.R
• B. 1) M.A = V.R 2) M.A < V.R
• C. 1) M.A > V.R 2) M.A < V.R
• D. 1) M.A = V.R 2) M.A > V.R

Answer 1

The correct option is B

1) M.A = V.R 2) M.A < V.R

1) For ideal machine : M.A = V.R 2) For practical machine : M.A < V.R
