If you have to fit three number 10 bars and 2 number 8 bars in a rectangular beam of 12 inch width you may need to use two rows. Given;
beam is 24 inch deep, the steel stirrup used is number 4,a 1 1/2 inch.
concrete cover on both sides. Sketch how you will place the bars and calculate the location of the effective depth. Place as many bars in the lower layers as possible.
an insulated tank contains pressurized air at 2000 kPa and 30 degrees celcius. The air is allowed to escape to the atmosphere (P=95 kPa, T=30 degrees celcius) until flow ceases. Determine the final temperature in the tank.
A 6.22-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.45 m/s and its y component of velocity is -2.88 m/s. (a) What is the kinetic energy of the object at this time
An afterburner has been selected to destroy 99.9% of the ethane (CH3-CH3)in a gas (mostly air) stream . if the residue time is 0.8 seconds and the pressure is 1.1 atmospheres in the after burner,
If the discharge is 500cfs, what power output may be expected from the turbine. Assume that the turbine efficiency is 90% and that the overall head loss is 1.5V 2/2g, where V is the velocity in the 7 ft penstock.
The traffic light shown in Figure 3 is supported by a system of cables. Points A and B are in a vertical plane which is parallel to x-z plane. Point C is in y-z plane. The traffic light has a mass of 75 kg.
estimate the mass and volume of sludge produced from unreated wastewater without and with the use of ferric chloride for the enhanced removal of TSS. Also, estimate the amount of lime required for the specified ferric schloride dose.
The member is supported by a pin at A aand a cable BC. If the load at AD is 300 lb, determine the x,y,z components of reaction at the pin A and the tension in cable b c
A hoist mechanism is attached to the back of a pickup truck. The crate being moved by the hoist shown below weighs 200 lbs. Note: Point A is directly above point B and the vertical distance between points A and B is 16 inches.
Determine the valve loss coefficient needed for h=20 ft. All losses except for the flow control valve are negligible. The area of the pipe is 5 times the area of the exit nozzle.
A core sample of basalt, 4 inches long and 2 inches in diameter, was tested in unconfined compression. The basalt is known to have a modulus of elasticity = 9.1 x 106 psi.
Electromagnetic radiation may be treated from the classical or the quantum-mechanical perspectives. Briefly compare these two viewpoints.
Given a saturated solution of calcium carbonate ( atequilibrium ) how many moles of calcium ion will remain insolution after the addition of 3.16x10^-4 M of Na2co3 at 25C?(Assume PH is constant)
