1.Two wooden members joined by a simple scarf splice and its diagram. The maximum allowable tensile stress in the splice is 75 psi. Determine the largest load P that can be supported and the corresponding shearing stress in the splice.
2.The mean annual precipitation for a certain 132 square mile watershed is 25 inches. Assume the 20 percent of the annual precipitation reaches the watershed outlet as stream flow. Determine the mean stream flow rate in ac-ft/yr, sfd/yr, and square meter/second
Calculate the moments M_A and M_B about point A for the forces applied at points A and B. Then, determine the resulting couple moment M_R. Assume that a positive moment produces a counterclockwise rotation whereas a negative moment produces a cloc..
Write out the final version of Hooke's Law which includes Young's Modulus. Draw the idealized Stress-Strain diagram for a material. On the drawing, please label: the yield stress, the plastic deformation, and the yield strain.
Use the Rankine cycle. The boiler operates at a 1000 kpa with a maximum temperature of 30 degrees Celsius. The condenser is isobaric and operates at -5 degrees Celsius.
Discuss the advantages and disadvantages of using 8-bit and 10-bit resolution for the analog-to-digital converter.
Suppose we want to estimate the average weight of adult males in greater metropolitan Atlanta area. We draw a random sample of 1,000 men from a population of 1,000,000 men and weigh them.
You are driving a car your metered fuel flow is 5.97x10^5 csf if at the speed you are driving you are getting 40mpg what is your speed in mph and ft/s need formulas.
what criteria should Zachary use evaluate the project ?
A wastewater treatment plant must disinfect its effluent before discharging the wastewater to a near-by stream. The wastewater contains 4.5*105 fecal coliform colony-forming units (CFU) per liter.
Compare the effectiveness of the zinc coating with a typical epoxy coating on reinforcement. How does the epoxy coating protect reinforcement and what happens if the coating is nicked.
An overflow spillway 1,600 feet long is designed to pass 120,000 ft3/s of water. A 1:20 scale model of the cross section of the structure is built in the laboratory. It is assumed that the flow is two dimensional so only a 1-foot section
The actual weight of the Rectangular Aluminum Beam (used in Task 3) is 25 grams, while the actual weight of the Square Aluminum Box Beam is only 5 grams.
A large steel tower is to be supported by a series of steel wires; it is estimated that the load on each wire will be 19,000N. Determine the minimum required wire diameter assuming a factor of safety 5 and that the yield strength of the steel is 900M..
