## Theory of Machine The Klein's method of construction for reciprocating engine mechanism

Is a simplified form of instantaneous center method
Utilizes a quadrilateral similar to the diagram of mechanism for reciprocating engine
Enables determination of Cariole’s component
Is based on acceleration diagram

## Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The minimum length of the coupler will be

95 mm
Slightly less than 45 mm
Slightly more than 45 mm
45 mm

Base circle
Pitch circle
Pitch curve
Prime circle

## Theory of Machine V-belts are usually used for

Short drives
Long and short drives
Long drives
None of these

## Theory of Machine Which of the following mechanisms produces mathematically an exact straight line motion?

Watt mechanism
Peaucellier's mechanism
Tchebicheff mechanism
Grasshopper mechanism
