Question

For an oscillatory machine, the force can be expressed as _________

(a) Cosine function and Sine function

(b) Cosec function

(c) None of the mentioned

(d) All of the mentioned

This question was addressed to me in quiz.

Asked question is from Machine Foundations in chapter Machine Foundations of Geotechnical Engineering II

Answer 1

The correct answer is (a) Cosine function and Sine function

The explanation is: Generally for an oscillatory machine (where the machinery vibrates because an unbalanced rotational force exists), the force can be expressed as a sine or cosine function, such as F0sinωt.
