Tension, stress in a pipe due to change in temperature.

When the hot water in a certain upstairs bathroom is turned on, a series of 18 "ticks" is heard as the copper hot-water pipe slowly heats up and increases in length. The pipe runs vertically from the hot-water heater in the basement, through a hole in the floor 5.0 m above the water heater. The "tick" are caused by the pipe sticking in the hole in the floor until the tension in the expanding pipe is great enough to unstack the pipe, enabling it to jump a short distance through the hoe. If he hot water temperature is 46'C and room temperature is 20'C, determine (a) the distance the pipe moves with each "tick" and (b) the force required to unstack the pipe if the cross-sectional area of the copper in the pipe is 3.55x10^(-5)m^2.

A steam pipe is covered with 1.50cm thick insulating material of thermal conductivity 0.200 cal s"1 cm"1 °C"1. How much energy is lost per second when the steam is at 200°C and the surrounding air is at 20.0°C? The pipe has a circumference of 800cm and a length of 50.0m. Neglect losses through the ends of the pipe.

A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm.
Determine the str

1. A pressure vessel is made of a cylindrical composite part produced by filament winding. Hoop winding is used in which the number of winding layer is 5 and the wall thickness for each layer is 1mm. The diameter of the vessel is 0.5m. The fiber material is known to be S-glass with a tensile strength of 4.5GPa, and the matrix m

3. Acme Tobacco is currently selling 5,000 pounds of pipe tobacco per year. Due to competitive pressures, the average price of a pipe declines from $15 to $12. As a result, the demand for Acme pipe tobacco increases to 6,000 pounds per year.
a. What is the cross elasticity of demand for pipes and pipe tobacco?
b. Assuming t

1) (a) If a rod of 1025 steel 19.7 in. long is heated from 68 to 176ï?°F while its ends remain fixed, determine the type and magnitude of stress that develops. Assume that at 68ï?°F the rod is stress free. (b) What will be the stress magnitude if a rod 39.4 in. long is used? (c) If the rod in part (a) is cooled from 68 to 14

A welded railway line, of length 15 km, is laid without expansion joints in a desert where the night and day temperatures differ by 50 K. The cross-sectional area of the rail is 3.6*10^-3 m^2, alpha= 8*10^-6 K^-1, and Y =2*10^11 Nm^-2
(a) What is the difference in the night and day tension in the rail if it is kept at consta

Water at 90 C flows through a 50mm bore steel pipe of wall thickness 8 mm. Ambient temperature is 18 C. Calculate the heat loss per metre length of pipe. Assuming that the surface heat transfer coefficients remain the same when a layer of hair felt 25mm thick is wrapped around the outside of the pipe, calculate the percentage
