## Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at

180° in the direction opposite to the rotation of the link containing the path
45° in the direction of rotation of the link containing the path
90° in the direction of rotation of the link containing the path
45° in the direction opposite to the rotation of the link containing the path

## Theory of Machine Sensitiveness of the governor is defined as the ratio of the

Mean speed to the maximum equilibrium speed
Sum of the maximum and minimum equilibrium speeds to the mean speed
Difference of the maximum and minimum equilibrium speeds to the mean speed
Mean speed to the minimum equilibrium speed

## Theory of Machine In locomotives, the ratio of the connecting rod length to me crank radius is kept very large in order to

Have perfect balancing
Minimize the effect of secondary forces
To start the locomotive quickly
Minimize the effect of primary forces

## Theory of Machine In an open pair, the two elements of a pair

Are not held together mechanically
Have a surface contact when in motion
Are kept in contact by the action of external forces, when in motion
Have a line or point contact when in motion
