a round steel alloy bar with a diameter of 0.75 in and a gauge length of 3.0 in was subjected to tension, with the results shown in the accompanying table. using a computer spread sheet program, plot the stress-strain relationship. from the graph, determine the young's modulus of the steel alloy and the deformation corrsponding to a 8225 lb load.
load(lb) Deformation 10^-4 in.2000 11.284000 22.546000 33.808000 45.0810000 56.3612000 67.66
Is the deformation equal to the strain?
The weight of the box is 20 lb and the coefficient of static friction between the box and the floor = 0.65. Neglect the weights of the bars. What is the largest value of the force F that will not cause the box to slip
The transportation agency would like to determine the maximum spacing of stations to allow trains to arrive no more than 5 minutes apart. 1. Draw a time-space diagram depicting the above scenario
When 0.3 m^3/s water flows through a 150 mm constriction in a 300 mm horizontal pipeline, the pressure at a point in the pipe is 345 kPa, and the head loss between this point and the constriction is 3 m.
Land is extremely valuable in this area therefore to win this job you need to consider innovative approach to reduce the waste areas
The forces F1, F2, and F3, all of which act on point A of the bracket, arespecified in three different ways. Determine the x and y scalar components of each of the three forces.
Find e1, e2, e3 for tendon to be concordant - find deflection at those location
Two tests are taken from the compacted mixture and checked for density. Core 1 had a density of 150 pcf and an air void content of 6.5 %. Core 2 had a density of 151 pcf. What is the air void content of core 2
An underground limestone mine with production of 12,000 tons/day will use trucks for the main haulage between an ore pass and a hoist skip pocket. The hauling distance is 5500 ft. The main haulage drift is horizontal and is 12.5 ft wide and 12.5 f..
The turbidity of the water ranges from 30 to 60 NTU, alkalinity exceeds 100 mg/L, hardness is about 50 mg/L as CaCO3, and the water also contains regulated synthetic organic compounds resulting from industrial discharges.
For a metal and wood structure, how would the economies of construction be obtained (pertaining to the mean and standard deviation of a probability of failure graph)?
The force of the expanding gases on a 0.02 kg bullet is given by f=f0-f.1*t . Initially stationary at x=0 , the bullet reaches a speed of 1000 kph by the time it exits the gun. f0 = 7000 N and f1=2.9*106 N/s.
