A bike with a mass of 250kg. The wheels each have a diameter of 500mm. The wheel has 8 spokes with a mass of 0.25kg for each spoke. The bike accelerates from 5m/s to 25m/s over a distance of 200m in 20 seconds.
Find the total work done by the bike.
Calculate the amount of power developed during the ride.
At another point in its journey, the bike travels at 80 km/h around a left-hand bend of radius 30m. Calculate:
The angular velocity of each of the wheels.
The moment of inertia of each wheel.
The magnitude and effect of the gyroscopic torque produced on the bike

Question5 Each of the two wheels of a motor bike have a mass of mw-11 kg, radius of rw 320 mm, and radius of gyration kw 0.24 m. The motor bike and rider with a total mass of m 208 kg travel round a bend of radius R = 80 m at a speed of 135 km/h. The engine rotates in the same sense as the wheels and at four times their speed. The engine rotating parts have a mass...
The car shown in the figure has mass m(this includes
the mass of the wheels). The wheels have radius r, mass
mw, and moment of inertia
I=kmwr2. Assume that the axles
apply the same torque ? to all four wheels. For
simplicity, also assume that the weight is distributed uniformly so
that all the wheels experience the same normal reaction from the
ground, and so the same frictional force.
Part A
If there is no slipping, a frictional force must...
A snow plough with a mass of m=8 metric tonnes (1 metric tonne=1,000kg) has an initial speed v1 =12 m/s is clearing snow. The retarding force the snow produces on the snow plough satisfies the force-displacement relationship,Fsnow = 900+6000x2where Fsnow is in Newtons and x is in metres. Each wheel have a radius of 0.5m and a mass moment of inertia of 3.75 kgm2. Assuming the wheels do not slip and friction can be ignored what is the speed of the snow plough after it travels a distance s=5m?
please give anwers ?
