A solid cylindrical bar, of 20 mm diameter and 180 mm long, is welded to a hollow tube of 20 mm internal diameter, 120 mm long, to make a bar of total length 300 mm. Determine the external diameter of the tube if, when loaded axially by a 40 kN load, the stress in the solid bar and that in the tube are to be the same. Hence calculate the total change in length of the bar. E = 210 KN/mm-

A particular table has three identical legs, and the surface area at the bottom of each leg in contact with the floor is 4.00 x 10m?. Assume the legs are uniformly spaced around the table, and the mass of the table is uniformly distributed with respect to the legs. The total mass of the table is 32.7 kg. What is the pressure (in Pa) on the bottom of each table leg (due to the floor alone, ignoring atmospheric pressure)? Pa Need Help? Read it
Water supplied to a house by a water main has a pressure of 3.00 × 105 N/m2 early on a summer day when neighborhood use is low. This pressure produces a flow of 20.0 L/min through a garden hose. Later in the day, pressure at the exit of the water main and entrance to the house drops, and a flow of only 8.00 L/min is obtained through the same hose. (a) What pressure is now being supplied to the house, assuming resistance is constant? (b) By what factor did the flow rate in the water main increase in order to cause this decrease in delivered pressure? The pressure at the entrance of the water main is 5.00 × 105 N/m2 , and the original flow rate was 200 L/min. (c) How many more users are there, assuming each would consume 20.0 L/min in the morning?
