The brass tube AB (E 5 105 GPa) has a cross-sectional area of 140 mm2 and is fitted with a plug at A. The tube is attached at B to a rigid plate that is itself attached at C to the bottom of an aluminum cylinder (E 5 72 GPa) with a cross-sectional area of 250 mm2. The cylinder is then hung from a support at D. In order to close the cylinder, the plug must move down through 1 mm. Determine the force P that must be applied to the cylinder

A car drives on a curved road that goes down a hill. The car's position is defined by the position vector,r={?[30.0cos(?10.0t)]i+[30.0sin(?10.0t)]j?(Azt)k} ftwhere Az=13.0ft/s. The image below shows the system projected onto the xy plane. What are the car's velocity and acceleration vectors at this position?

A vineyard owner is planting several new rows of grapevines, and needs to know how many grapevines to plant in each row. She has determined that after measuring the length of a future row, she can use the following formula to calculate the number of vines that will fit in the row, along with the trellis end-post assemblies that will need to be constructed at each end of the row:V = R 2E / SThe terms in the formula are:V is the number of grapevines that will fit in the row.R is the length of the row, in feet.E is the amount of space, in feet, used by an end-post assembly.S is the space between vines, in feet.Write a program that makes the calculation for the vineyard owner. The program should ask the user to input the following: The length of the row, in feet The amount of space used by an end-post assembly, in feet The amount of space between the vines, in feetOnce the input data has been entered, the program should calculate and display the number of grapevines that will fit in the row.

A polluted stream contaminated with agricultural run-off discharges into a lake. The lake contains 10 x 106 m of water. The stream flows at 120 ft / min and contains 0.40 mg/L of phosphorous (P) and 0.01 ug / L of a regulated pesticide. A larger river flows into the lake with a flow rate of 24,000 ft/min containing 0.001 mg/L of P and no detectable levels of the pesticide. Assume phosphorous is a conserved pollutant and the herbicide as non-conserved with a decay coefficient k = 3.23 x 10-4 mindue to chemical destruction by sunlight in the lake. A river flows out of the lake at the opposite end. a. Assuming the lake is well mixed, calculate the steady state phosphorous concentration in the lake in units of ug / Land ppb (parts per billion) b. Assuming the lake is well mixed, calculate the steady state pesticide concentration in the lake in units of ug/L and ppt (parts per trillion). c. What is the residence time of water in the lake?
