A jet of water of diameter 75mm moving with a velocity of 25m/s strikes a fixed plates in such a way that the angle between the jet and plate is 60? find the force exerted by the jet on the plate. (a) In the direction normal to the plate and (b) In the direction of the jet
a tank is filled with oil (specific gravity 0.8) and water to a depth of 10 meter and 6 meter respectively. Find the resultant force from all fluids acting on the gate of 1.8 meter by 9 meter.
Explain how the different physical characteristics and moisture content of soil lead to the different angles of repose, swell, and shrinkage factors. Explain how these factors affect excavation operations and costs.
The aluminium wire has a radius of 1.1mm. What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
Design a riveted end plated Connection between a beam ISHB-300 and the flange of the Column ISHB-200 to transfer a vertical factored shear of 125 kN and a factored hogging bending moment of 125kNm.Use Shop rivets of 20mm dia.
water flows from a lake as is shown in fig. p8.40 at a rate of 4.0 cfs. is the device inside the building a pump or a turbine? Explain and determine the horsepower of the device. neglect all minor losses and assume the friction factor is .025
You are a Project Manager on site where work for 3K.m. long Tunnel has been undertaken. The site is remote and takes about 2 days travel to nearest town. Supervisors, Technicians & Skilled Workers are engaged in dangerous / hazardous work.
Two carts with masses of 4.72 kg and 2.84 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.97 m/s respectively. The carts stick together after colliding head-on. Find the final speed.
Due to an error, the length L shown was 1.795 m instead of 1.80 m, thus there is a gap of 0.5 cm, which makes it difficult to bolt the bar on the structure. The engineer suggests the bar is heated up by - Delta in order to close the gap.
Crude oil at 20 degrees C fills the space between 2 concentric cylinders 250mm high with diameter of 150 and 156mm. What torque is required to rotate the inner cylinder at 12 rev/min
Calculate the (maximum) design load on a hollow AISI 1020 steel shaft with an outside diameter of 2.5 inches and an inside diameter of 2 inches. Assume a safety factor of 2.
The telescope of the instrument is 5.25 ft above the ground station, whose elevation is 415.65 ft. What is the elevation of the tip of the spire? (Ignore atmospheric refraction and earth curvature)
Select the number and size of reinforcing bars required to resist a total factored moment of 180 ft. kips for a rectangular section with b = 12 in., d = 19.5 in., h = 24 in., f'c = 4 ksi, and fy = 60 ksi.
