The product in this case is the solution to problem 15.1.10 from the collection of Kepe O.?.

The task is to calculate the work of sliding friction forces when braking a disk of radius r = 0.1 m for 10 revolutions. To do this, it is necessary to take into account the forces F1 and F2, equal to 100 N, with which two brake pads are pressed against the disc, as well as the sliding friction coefficient of the brake pad on the disc f = 0.3.

The problem can be solved as follows:

1. Find the total work of friction forces for 10 revolutions of the disk. To do this, we use the formula for the work of force: A = F * s, where F is the sliding friction force, s is the path traveled by the point of application of the force. The path s traversed by the point of application of force in 10 revolutions is equal to 2 * pi * r * 10, where r is the radius of the disk. The sliding friction force is equal to F = f * N, where N is the normal reaction force, equal to the sum of the forces F1 and F2. Thus, the total work of friction forces will be equal to A = F * s = f * N * 2 * pi * r * 10.

2. Substitute the known values ​​into the formula and solve the equation: A = 0.3 * (100 + 100) * 2 * pi * 0.1 * 10 = -377 J.

Answer: the work of sliding friction forces when braking a disk of radius r = 0.1 m for 10 revolutions is equal to -377 J.
