Chapter 3.5, Problem 105P
Magnetic tape under a tension of 10 N at D passes around the guide pulleys and through the erasing head at C at constant speed. As a result of a small amount of friction in the bearings of the pulleys, the tape at E is under a tension of 11 N. Determine the tension T in the supporting spring at B. The plate lies in a horizontal plane and is mounted on a precision needle bearing at A.

The mechanism shown is used to carry out experimental tests on different industrial springs that are placed between the wall and point A. The rigid reinforcement that holds the spring at A moves through the horizontal beam by means of the 4 frictionless rollers. The piston CD is compressed by stretching the spring at A. For the situation in the position shown the spring is stretched a distance s and has an elongation constant of 2000N / m. The weight of the system can be considered negligible.
Determine:
1.The magnitude of compressive force exerted by the piston at the position shown.
2.The magnitude of the force experienced by the bolt at E.
The 10 N cylinder moves in a friction tube. Spring constants are k1 = 150 N / m and k2 = 200 N / m. When the system is at rest, d = 0.5 m. The system rotates around a fixed z-axis. In the case where d = 0.12 m, what is the coefficient of friction for the cylinder to have a constant velocity of 9.825 m / s?
5. A box with a mass of 100 kg was originally attached to the spring at position A. After that, pressure was applied to the box until The spring compresses to a distance of X - 1 m and releases it, causing the box to move upwards along the inclined floor. If the incline has and = the coefficient of friction uk = 0.3, find the box that can travel along the incline for a maximum distance in meters.
