Question 1
The slide crack mechanism of a sports motorcycle is shown in Figure 1. The net force
experienced by the vertically positions piston is 2257 N. Whereas, the piston has
a diameter, and the stroke length is 100 mm and 120 mm, respectively. The
linear velocity of the piston is 5.3 m/s and the angle between the line of action of
the piston and the crack (OB) is 0 = 20°.

The speed of the engine mechanism shown in Figure 1 is controlled by the Porter
governor. All arms of the governor are 20 mm and are hinged at a distance of 4
mm from the axis of rotation. The mass of each ball is 100 g and the mass of the
sleeve is 500 g. The governor sleeve begins to rise at 40 rad/s. when the links
are at an angle of 5° to the vertical. Assuming the friction force to be constant
3.1.
Draw the port governor mechanism and clearly lable it.
3.2. Calculate the minimum speed of rotation (in rad/s) when the inclination of the (14) arms to
the vertical is 10°.
