The weight of a vehicle is 14 kn. the wheel base is 3 m and the centre of gravity is 650 mm above the road surface. the track width of the vehicle is 1,5 m. the vehicle must negotiate a curve which is banked at 20° with a radius of 130 m. assume a coefficient of friction between the wheels and the road surface of 0,6. determine the maximum speed in km/h at which the vehicle can travel around the curve safely.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
