the gauge pressure is 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.)

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)

Force exerted by a truck is 500000N and the pressure on the ground is 2500000Pa. Calculate the area of contact of tyres with ground?

The weight of a rider, driving scooter is assumed to be evenly distributed on both the tyres.The area of contact of each type with the ground is 10cm^(2) . If the pressure inside the tyres is 3 bar, find the mass of the rider (g=10ms^(-2))

The drwing shows a bicycle wheel of radius r, resting against a small step whose height is h = r//5 . A clockwise torque increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. Let this torque be T. What is the magniitude of the horizontal component of the acceleration of the centre of the wheel when a torque of 2T is applied? Assume that the wheel doesn't slip at the edge of the step when this torque is applied (ignore the mass of the spokes).

A person measure the presssures of his car tyre to be 2 times 10^5 Pa At that time the temperature and pressure of the atmosphere are 27^@C and 1 times 10^5 Pa respectively. Then he travels to another city where the temperature and pressure of the atmosphere are 12^@C and 6.7 times 10^4 Pa respectively. Them what will be the pressure of his car tyre at that time. Assume the volume of the tyre is same in both cases.

A track consists of two circular pars ABC and CDE of equal radius 100 m and joined smoothly as shown in figure.Each part subtends a right angle at its centre. A cycle weighing 100 kg together with rider travels at a constant speed of 18 km/h 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 road and the tyre, which will ensure that the cyclist can move with constant speed? Take g=10 m/s^2
