## Machine Design The face of the tooth is the

Surface of the tooth below the pitch surface
Width of the tooth measured along the pitch circle
Surface of the top of the tooth
Surface of the tooth above the pitch surface

## Machine Design In the case of an elastic bar fixed at upper end and loaded by a falling weight at lower end, the shock load produced can be decreased by

Remain unaffected with cross-section area
Decreasing the cross-section area of bar
Increasing the cross-section area of bar
Would depend upon other factors

## Machine Design Which of the following statement is wrong for a connecting rod?

The most suitable section for the connecting rod is T-section
If Ixx > 4 Iyy, the buckling will occur about Y-axis
If Ixx < 4 Iyy, the buckling will occur about X-axis
The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy
