The steel post BC supports the right end of the beam that has a uniform distributed force q. The post is a wide-flange section W310 x 74 which is built-in at the base C, but free to pivot at B. Allowing for buckling in either plane, determine the critical distributed force q at which the post first buckles. Take
A conversion of land from tomato farming to cotton is planned. Is it true that less water will be used to supplement rainfall based on one growing season ?
A spherical gas container made of steel has a 5-m outer diameter and a wall thickness of 6 mm. Knowing the internal pressure is 350 kPa, determine te maximum normal stress and the maximum shearing stress in the container.
A simple way to model air pollution over a city is with a box model that assumes complete mixing and limited capability for the pollution to disperse horizontally or vertically except in the direction of the prevailing winds
A concentrated moment is applied to the free end. Determine the maximum bending stress on the outside surface of the cylinder and the maximum bending stress on the inside surface of the cylinder.
determine the time t required to bring the payload from its stowed position at θ = 0 to its deployed position at θ = 90° if the torque is applied for the first 45° of travel and then reversed for the remaining 45° to bring the payload to a stop ()
Draw a P-V diagram for pure component and label appropriate points such as superheated region, isothermal line, etc.
Aerotron Electronics is considering purchasing a water filtration system to assist in circuit board manufacturing. The system costs $40,000. It has an expected life of 7 years at which time its salvage value will be $7,500.
Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of = 74.0 with the floor and rope segment CD
A suspended solid particle of density 2200 kg/m3 is moving at 0.25 m/s of horizontal and 0.15 m/s of vertical velocity respectively in a sedimentation tank. If the depth of the tank is 2.0 m what should be the length of tank to trap the particle i..
During an engine test on the ground, a propeller thrust T = 4000 N is generated on the 1500 kg airplane with mass center at G. The main wheels at B are locked and do not skid; the small tail wheel at A has no brake.
A short 60mm diameter circle bar is made of material for which the maximum safe compressive strees is 80 MPa and the maximum safe shearing strees is 30 MPa.
In a rectangular channel of 12 m width, water flows at a rate of 150 cms. At the end of the channel, there is a horizontal concrete apron of 12 m width, on which the water depth is 3 m. Will a hydraulic jump formed in the channel and why? What is the..
