A loaded lory has a total weight of 12000 kg . Its 6 tyres are identical and show an air pressure of `50 kg wt//cm^2` each. If the load is distributed equally on all 6 tyres. Find the area of contact of each tyre with the road.

The gauge prerssure in both the tyres of a bicycle is 7.0 xx 10^5 Pa If the bicycle and the person riding it have a combined mass of 100 kg. find the area of contact of each tyre with ground.Use g = 10 ms^(-2)

a car weight 1200 kg. This weight is evenly distributed on 4 wheels. If the pressure in each tyre is 15kg((wf)/(cm^2)) . What is the area of each tyre in contact.

Tyre of a bicycle has voulme 2xx10^(-3)m^(3) Initially the tube is filled to 75% of its volume by air at atmospheric pressure of P_(0)=10^(5)N//m^(2) . When a rider rides the bicycle the area of contact of tyre with road is A=24xx10^(-5)m^(2) . The mass of rider with bicycle is 120kg. The number of stokes which delivers, V=500cm^(3) volume of air in each stroke required to infalte the tyres is [Take g=m//s^(2) ]

A track consister of two circular parts ABC and CDE of equal redius 100m and joined smoothly as shown in Fig .Each part subtends a right angle at its center A cycle weighing 100 kg together with the rider travels constant speed of 18 kmh^(-1) on the track a. Find the normal contact force by the road on the cycle when it is at B and at D. b. Find the force of friction exerted by the track on the tyres when the cycle is at B,C and D. c. Find the normal force between the road and the cycle just before and just after the cycle crosses C d. What should be the minimum friction coefficient between the mad road and the tyre , which will ensure that the cyclist can move with constant speed ?

the gauge pressure in both tyres of a bicycle is 690 k Pa. If the bicycle and the rider have a combined mass of 90 kg. what is the area of contact of each tyre with the ground? (assume that each tyre supports half the total weight of the bicycle.)
