11.9 (A/B). Develop from first principles an expression for the instantaneous stress set up in a vertical bar by a
weight W falling from a height h on to a stop at the end of the bar. The instantaneous extension x may not be
neglected.
A weight of 500 N can slide freely on a vertical steel rod 2.5 m long and 20 mm diameter. The rod is rigidly fixed at
its upper end and has a collar at the lower end to prevent the weight from dropping off. The weight is lifted to a
distance of 50 mm above the collar and then released. Find the maximum instantaneous stress produced in the rod.

- "pls answer in 20 mins"arrow_forwardThe frictional resistance of a thrust bearing decreases as the shaft and bearing surfaces wear out. It is generally assumed that the wear is directly proportional to the distance traveled by any given point of the shaft and thus to the distance r from the point to the axis of the shaft. Assuming then that the normal force per unit area is inversely proportional to r , show that the magnitude M of the couple required to overcome the frictional resistance of a worn-out end bearing (with contact over the full circular area) is equal to 75 percent of the value given by Eq.
