A girder that carries a uniformly distributed dead load of 1.7 K/ft plus its self-weight and three concentrated live loads of 15 kips at quarter points of that 36 ft span is to be sized. using A992 steel, determine the lightest W-shape to carry the load with lateral supports provided at the supports and loads point . use the correct Cb and design by LRFD.
A stainless steel (304) bar with a cross section of 0.2" x 0.4" is cut to a length of 30" and placed between two immovable walls at a temperature of 40 degrees F. The operating temperature for the bar is 200 degrees F.
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
Given that the seperation distance between the charges is 5m, q1 = -3q2, find the position where the net electric field is zero. Do not use infinity.
What is the solution if foundation bolt cut by some way from their bottom of skid, i mean skid base than how to keep another bolt etc for tightness of skid along with pump-motor already fittied with pipe and other fitting's too..
What are minerals? Sketch different types of mineral crystal forms and list different types of rock forming minerals. Describe with examples the importance of mineral identification in engineering applications.
A hydraulic transition 100 ft long is used to connect two rectangular channels, 12ft and 6ft wide. The design discharge is 500 cfs, mannining coefficient=.013 and the slopes of the channels are both .0009.
Calculate the stress at failure of a concrete test cylinder with a measured diameter of 152.4 mm and a recorded load of 371,426N. Units of ksi.
An object is held in the air 30m above ground and released. Assume the drag force due to air resistance is given by Fd = 1.0Vy. What is the mass of the object necessary so that it reaches ground in 3s
The road has 12-ft lanes. Due toexpensive excavation, it is determined that a maximumof 34 ft can be cleared from the road's centerline toward the inside lane to provide for stopping sight distance.
Determine the critical load of a round wooden dowel that is 0.9m long and has a diameter of (a) 10mm (b) 15mm. Use E=12GPa
determine the stresses in the steel and concrete under the service loads
Under these conditions flow is expected to be turbulent, but for a clean air, very smooth enterance (with guided vanes) to the tube and no tube vibration, it may be possible to maintain laminar flow.
