## Theory of Machines Internship Test

Intern has to take Theory of Machines internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Theory of Machines topic.

1. A linkage containing a screw pair is an example of
(A) Planar mechanism
(B) Spatial mechanism
(C) Flexure mechanism
(D) Spherical mechanism

Explanation: Relative motion within a screw pair is helical. It is not constrained to one plane. Hence, a linkage containing a screw pair is an example of spatial mechanism.

2. Mobility is different than the number of degrees of freedom. True or false?
(A) True
(B) False

Explanation: The mobility or number of degrees of freedom of a rigid body is defined as the number of independent movement the body has. The number of parameters that must be controlled independently to get the device in a particular position is mobility. Mobility and number of degrees of freedom are the same thing.

3. The relative motions between different links changes due to the process of inversion. True or false?
(A) True
(B) False

Explanation: The relative motions between the various links do not change through the process of inversion, but the motions measured with respect to the fixed link change. Thus, the given statement is false.

4. If the link opposite to the shortest link is fixed, what type of mechanism is obtained?
(A) Double crank mechanism
(B) Linkage is not planar
(C) Double rocker mechanism
(D) Crank rocker mechanism

Explanation: When the link opposite to the shortest link if fixed, the shortest link is able to make a complete revolution but the two links adjacent to it oscillate between limits and are called rockers. Thus, this mechanism is called as double rocker mechanism.

5. __________ mechanism is a crossed four bar chain mechanism in early steam engines to guide the piston rod in a cylinder to have an approximate straight line motion.
(A) Peaucellier’s
(B) Chebychev’s
(C) Grasshopper
(D) Watt’s

Explanation: Watt’s mechanism is a four bar chain mechanism and was used by Watt in steam engines so as to guide the piston rod into a cylinder to have a straight line motion. Due to the rotation motion of the longer links, the centre of the shorter link traces an approximate straight line.
