A car of mass 850 kg travels round an unbanked horizontal curve of radius 35 m. The limiting coefficient of friction between the tyres and the road is 0.65. The track width of the car is 1.65 m and its center of gravity is central and at a height of 0.8 m above the road surface. Show that the car is likely to skid rather than overturn if the speed is excessive and calculate the maximum speed in km h 1 at which it can travel round the curve. What will be the reactions of the inner and outer wheels at this speed?
Superimpose a uniform ?ow parallel to the x-axis of 10 m=s and a source at the origin of strength q ¼ 10p m2/s. (a) Write the velocity potential f and stream function c.
For the pendulum shown in the figure,the restoring torque due to gravity is given by T=mgLsin(thita). Derive the linearised equation about the operation point thita=0.
