Question

There are no free body diagram used in the calculations of the forces at the supports and at the joints. Because the free body diagrams of a machines are so hard to be made.

(a) The first part of the statement is false and other part is true

(b) The first part of the statement is false and other part is false too

(c) The first part of the statement is true and other part is false

(d) The first part of the statement is true and other part is true too

I had been asked this question in final exam.

This intriguing question originated from Frame and Machines topic in chapter Structural Analysis of Engineering Mechanics

Answer 1

Right answer is (b) The first part of the statement is false and other part is false too

Best explanation: There is a great need of the making of the free body diagrams in the calculations of the forces that are being acted upon the joints. This helps in making of the design of the machines and the frames. These are very important quantities that are being determined.
