## Theory of Machine The indicator using Watt mechanism is known as

Simplex indicator
Thompson indicator
Thomson indicator
Richard indicator

## Theory of Machine The D-slide valve is also known as

Piston slide valve
None of these

## Theory of Machine The frictional torque transmitted in a conical pivot bearing, considering uniform pressure, is (where R = Radius of shaft, and α = Semi-angle of the cone)

(3/4) μ W R cosecα
μ W R cosecα
(2/3) μ W R cosecα
(1/2) μ W R cosecα

## Theory of Machine In a single slider crank chain

Three are turning pairs and one is a sliding pair
Two are turning pairs and two are sliding pairs
One is a turning pair and three are sliding pairs
Each of the four pairs is a turning pair

## Theory of Machine The dynamic friction is the friction experienced by a body, when the body

Is at rest
None of these
Is in motion
Just begins to slide over the surface of the other body

## Theory of Machine The frictional torque transmitted in a truncated conical pivot bearing, considering uniform pressure, is

(1/2). μ W cosecα [(r₁³ - r₂³)/(r₁² - r₂²)]
(2/3). μ W cosecα [(r₁³ - r₂³)/(r₁² - r₂²)]
(2/3). μ W cosecα (r₁ + r₂)
(1/2). μ W cosecα (r₁ + r₂)
