The classification of the toothed wheels is shown according to the position of the axes of the shaft. Choose the type of toothed wheels which doesnot comes under this classification.

If the radius of the pitch circle of the gear profile is 50 mm and the value of addendum is 5 mm. Whatwill be the radius of the addendum circle?

What is the value of the sensitivity of the isochronous governor?

The curve formed by the face and the flank of the tooth is known as ............

The strength equation for the rivet in the single shear is given by ..............

The substance used in the reduction offriction between the two surfacesin the relative motion is known as ..........

Choose the principle which is NOT used in the solution making of the problem relatedto friction.

The term G and @ is also known as ............ and .......... respectively in the torsion equation $$\frac{T}{J} = \frac{\tau}{R} = \frac{G \theta}{L}$$

The value of the coefficient of friction between the box and the surface is 0.20 which prevents the box from sliding. If the box decelerates with ‘a’ (m/s$$^2$$), then calculate the deceleration, if the force applied is ‘ma’.

Calculate the value of shear stress (MPa) in the solid circular shaft of diameter 0.1 m which is subjected to the torque of 10 kNm.
