The applied load on the piston of an offset slider-crank linkage shown in Fig. I is
100 14, and the coefficient of friction between the slider and the guide 18 0.27,
using graphical method determine the magnitude and sense of torque applied on
OA for the static equilibrium of the linkage.

2 Fig. 2 shows a four bar linkage on which various forces acting and their directions (10)
are shovv'n. Determine the magnitude and direction of the torque applied on the
link OIA to keep the equilibrium of the linkage. Also determine the magnitude
and direction of the forces ransmitted to the frame of the linkage. Use Matrix
method.

3 Two 20° straight bevel gears have a module pitch of 4mm, and 24 and 48 teeth (10)
respectively. The tooth face width is 50 mm. The pinion rotates at 1000 rpm and
transmits 5 kW. The shafts are at 90°. Determine the components of the gear force
and show these on a sketch of the gears.
