Problem 6P

A bicycle with tires 68 cm in diameter travels 8.0 km. How many revolutions do the wheels make?

Solution 6P We need to calculate the torque about an axis that passes through the point Step 1: The torque acting on the rod an axis passing through the point where the pin enters the rod is equal to the sum of the torques due to weight of the rod. Where written as, = + mass Net rod Net = ( g)R + g) Where, M s the mass of the rod, m is the hanging mass R is the distance from center of the rod to pin point r is the distance from far end to rod to pin point
