When calculating the complete vector on the central section of the dam wall, do you include the 8m for the radial gates? Also, how do you calculate the length of the sides for the pressure prism of the uplift? The face is 142 + 8, is the other side 142/sin57? Question 2 A large concrete gravity dam, storing water, has a central drum gate and four (4) radial gates installed on its central spillway section to control releases from the...
Materials fracture when the force per unit area, called STRESS, exceeds a critical value. In general, the critical stress depends on the direction as well as the magnitude of the force. For example, bones break differently when subjected to torsional (twisting) stress than when subjected to compressional (or squeezing) stress. Let us consider compressional stress. Wet human bone for 20-39 year olds has an ultimate compressive strength of 1.6x104N/cm2 [8]. Consider a person who falls from a height to the...

A previously healthy 18-year-old woman presented to the emergency department with a two-day history of progressive pain in her left thigh. One day before the onset of her left thigh discomfort, the patient and her mother had an altercation that involved her mother biting her left thigh. At the time of presentation, the patient had an oral temperature of 37.5ºC, a blood pressure of 136/80 mmHg and a heart rate of 106 beats/min. Her left thigh was erythematous (redness of...
Even when shut down after a period of normal use, a large commercial nuclear reactor produces heat at the rate of 162 MW by the radioactive decay of fission products. This causes a rapid increase in temperature if the cooling system fails. Answers are NOT 12650 and 0.181 for #1. Even when shut down after a period of normal use, a large commercial nuclear reactor produces heat at the rate of 162 MW by the radioactive decay of fission products....
Only need help with Question 3, thanks ;) The actual velocity profile is given by the Poiseuille equation as follows: ()APR where AP is the pressure driving force, R is the tube radius, u is the fluid viscosity, Lis the tube length, and r is the radial position of interest. A couple of notes: . Assume that the fluid has a viscosity similar to water (rester 103 Pa s) Winter 2019 Il. The radial position r is defined to be...
1.) Saltwater is slightly denser than fresh water. If you swim below the surface in saltwater, will the pressure be greater than in freshwater at the same depth?/1 2.) Suppose that you balance a5 kg ball on the tip of your finger, which has an area of 0.0001 m. Find the pressure on your finger in Pa Don't forget to first find the force of gravity on the ball/3 3) Why isn't there a horizontal buoyant force on an object...
Please answer exercise questions 2 & 7 and explain how you got the answers. 132 Homework 3 Due Tuesday January 29 (if possible...) Read sections 10-1 through 10-5. Chapter 10 Questions: 2, Exercise 2: A circular suction cup with a radius of 4.50cm has one atmosphere pushing down on one side, a force F pulling up, and a vacuum underneath. What is force F required to cancel the force of the (one) atmosphere of pressure? (Ans, between 600 and 700N,...
Problem 4: Read Appendix 2 below (Sec. 1.4.1 of Kasap) and then solve. A metallic back contact is applied to the CdTe solar cell of Problem 1 using a set up similar to that described in Figure 1.74 (b) on the next page. To form the metallic back contact, two evaporation sources are used, Cu and Au. An initial 3 nm layer of Cu is deposited first and then 30 nm of Au is deposited. After these depositions, the sample...
