The forewheel of a carriage makes 6 revolutions more than the rearwheel in going 120 m. If the diameter of the forewheel be increased by `1/4` its present diameter and the diameter of the rearwheel be increased by `1/5` of its present diameter, then the forewheel makes 4 revolutions more than the rearwheel in going the same distance. Find the circumference of each wheel of the carriage.

Solve the following problrms using two variables: The fore wheel of a tractor makes 120 revolutions more than the rear wheel in going 720 m. If the diameter of the fore wheel is doubled and the diameter of the rear wheel is increased by 1 1/2 times the present diameter, then the fore wheel makes 20 revolution more than the rear wheel in going the same distance . Find the circumference of each wheel.

The diameter of a flywheel is 1.2 m and it makes 900 revolutions per minute. Calculate the acceleration at a point on its rim

An iron tyre is to be fitted onto a wooden wheel 1 m in diameter. The diameter of tyre is 6 mm smaller than that of wheel. The tyre should be heated so that its temperature increases by a minimum of (the coefficient of cubical expansion of iron is 3.6 xx 10^-5/^@C)

A coil of 2000 turns and of mean radius 5 cm, makes 300 revolutions per minute around one of its diameters in a uniform magnetic field of induction 2.5 xx 10^-5 Wb/m^2 at right angles to its axis of rotation .Calculate the maximum e.m.f. induced in the coil and also its r.m.s. value.

Two full turns of the circular scale of a screw gauge cover a distance of 1 mn on its its main scale . The total number of divisions on the circular scale is 50. Further m it is found that the screw gauge has a zero error of - 0.02 mm . While measuring the diameter of a thin wire , a student notes the main scale reading of 4 mm and the number of circular scale divisions in line with the main scale as 37. The diameter of the wire is
