A 40 mm diameter solid brass shaft in a marine vessel is subjectedto a simultaneous torsion of T=250 N.m and axial thrust of P=25kN.
(a) Show the combined state of stress on the surface element of theshaft.
(b) Draw a Mohr's circle for the state of stress shown in part(a).
(c) Determine the magnitude and direction of the principal stressesand show these on a correctly oriented element.
(d) Determine the maximum shearing stress and any coexisting normalstress on the element and show these on a correctly orientedelement.
a horizontal cylindrical tank 4 ft in diameter and 10 ft long is full of water. find the work done in pumping the water to a point 4 above the top of the tank.
An automobile company is planning to build a 1.8 million square foot factory in Auburn. Estimate the expected number of trip ends at the factory on an average weekday.
A proposed combined cycle power plant is shown below. A gas turbine engine, the topping cycle, takes air at state 1 (T=300 K, P=100 kPa) and compress it irreversibly (hc=0.87) to state 2.
A brass cube (E=100 GPa, v = 0.25(Poisson's ratio)) is 100 mm long per side. A compressive force of 100kN is applied to one side, while a tension force of 200 kN is applied to a second side.
You are designing a new thermometer using Galinstan, an alloy of gallium, indium, and tin that is a liquid at normal living temperatures. The coefficcient of thermal expansion is 190*10^-6 (1/kelvin).
The velocity along a pathline is given by V (m/s) = s^2 x t^(1/2) where s is in meters and t is in seconds. The radius of curvature is 0.5 m. Evaluate the acceleration along and normal to the path at s = 2m and t = 0.5 seconds.
a simple rankine cycle uses water as the working fluid. the boiler operates at 6000 kpa and the condenser at 50 kpa. at
what are the main points which create necessity of new railway line? explain in detail different types of surveys conducted in railway work.
A course has true azimuth of 157 degrees 15 minutes and a length of 325 feet. What is the departure of the course
The 5-m long cantilever beam using a W410 x 67 standard wide flange section has a distributed load of 1200 N/m placed on it. It is also supported by a cable at B, of length 2 m with a 7 mm2 cross sectional area. What is the force in the wire
Eventually, the teen gets bored with this new game and shedecides to throw the tomatoes straight down at an initialvelocity of 15 m/s. Now, how long does she need to wait after seeing the cars to hit them at the same height?
A solid circular shaft AC of total length L=L1+L2 is fixed against rotation at ends A and C and is loaded by a tourqe T_b at joint B. If the diameter of the two segements of the shaft are in ratio d2/d1
