On a bicycle, why does my back tyre wear so much more quickly than the front?
1 Answer
Saurabh Koranglekar
Because the frictional resistance at the rear wheel balances both the frictional resistance at the front wheel and the wind resistance, the frictional resistance at the rear wheel is strictly larger in amplitude than the frictional resistance at the front wheel unless the bicycle is not moving, so there must always be greater wear of the rear tyre

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
