Two triaxial compression tests were performed on two prepared samples of the same limestone. At a confining pressure of 2000 psi, the first sample failed at 9000 psi. Then at a confining pressure of 5000 psi, the other sample failed at 21000 psi.
(a) plot the 2 test results on a shear stress-nomal stress diagram and draw in the Mohr envelope.
(b)determine the slope angle of the Mohr envelope.
(c) what is the 'So' value? (shear strength or cohesion) (d) what was the shear stress on the failure plane at failure for both tests?
A tub of a washing machine is rotating at 50 rad/s when the power is turned off. If it takes 15s for the tub to come to rest, determine (a) the constant angular deceleration, and (b) the total number of revolutions the tub makes.
Show or formulate the shear and bending moment expressions for each board, and plot/draw the shear and bending moment diagrams of the boards.
Immediately after the bouncing golf ball leaves the floor itscomponent of velocity are Vx= 0.662 m/s and Vy= 3.66 m/s. determinethe horizontal distance from the point where the bal
An SAE steel wire (1mm diameter) is coated with another cover to form a composite material with diameter of 2 mm. a) determine the elastic modulus of the composite material;
Develop a table that shows: 1) How many gallons of water are contained in the tank if the volume is measured in increments of 1 ft from the bottom to the top. 2) The mass of water at each increment, expressed in lbm.
A quality characteristic is monitored by a control chart designed so the probability that a certain out-of-control condition will be detected on the first sample following the shift to that state is 1-beta.
A rapid-mixing basin is to be designed for a water coagulation plant, and the design flow for the basin is 4.0 MGD (million gallons per day). The basin is to be square with a depth equal to 1.25 times the width.
Considering both temperature and pressure to be variables, what is the largest number of phases that can coexist at equilibrium in a binary alloy?
A galvanized (zinc-coated) steel sheet is found to uniformly corrode with an average current density of 1.4 X 10-7 A/cm2. How many years will it take to uniformly corrode a thickness of 0.030 mm of the zinc coating
The beam has a flange width b=8 in. If the maximum bending stress is not to exceed σallow=22 ksi, determine thegreatest weight of the machine that the beam can support. The center of gravity for the machine is at G, and the supports at Band C are smo..
What is the velocity head expressed in atmospheres for a rapid filter operated at a surface loading rate of 475 m/d when the local porosity is 0.40?
A W24X94 beam on a 6 ft span underpins a column that brings 110 kips dead load and 280 kips live load to its top flange at a location 2.5 ft from the left support.
