A 125lb bowling ball is suspended from point C with rope CE. A second rope (ABC) is tied to point C and wraps around pulley B toward point A. Spring CD is used to hold the position shown. Determine the stretched length of CD if the spring coefficient is 200lbs/ft and the unstretched length is 2.6 feet. ABC is independent of rope CE. Use statics to solve.
At a local engineering firm, a supervisor thinks about buying a new copy machine for $700 but only wants to keep it for 3 years. Using the DDB find the book value of the machine at the end of 2 years.
Based on given soil data. Soil is a loam with grain the #200sieve. The Liquid Limit = 29, Plastic Limit = 24, friction angleφ = 25 degree, cohesion c = 0.21 tons/sf, unit weight γ=124lb/ft3.
Water flows from a drain spout with an initial velocity of 2.5 ft/s at an angle of 15o with the horizontal. Determine the range of values for the distance d such that the water will enter the trough BC.
The problem belongs to Civil Engineering and it is explain about a building which is constructed with the method of dropping fossil fuel consumption and to reduce the carbon footprint of the building.
compose a list here of the geological terms that you encounter in this reading that you could not define and explain in a test situation.
Assume you are an observer standing at a point along a three- lane roadway. All vehicles in lane 1 are traveling at 30 mi/ h, all vehicles in lane 2 are traveling at 45 mi/ h, and all vehicles in lane 3 are traveling at 60 mi/ h.
Write a short presentation on a Drainage project, How you will do it , what program you will use.
At normal atmospheric conditions, approximately what pressure in psi must be applied to water 70 F to reduce its volume by 2 %
1.a well water with a total hardness of 10.76 ppm is to be used for a pharmaceutical industry which requires finished
A tank with a 3m diameter has an 8 cm orifice at the bottom. The tank is currently filled with water to a height of 2.5m above the orifice. If the orifice is opened.
The static pressures upstream and downstream of the screen are 0.2 and 0.15 psi and are uniformly distributed over the flow cross section area. Neglecting the force exerted by the duct wall on the flowing air, calculate the screen drag force.
A heavy Machine is lowered into a pt by means of a rope wrapped around an 8" diameter stationary pole placed horizontally across the top of the pit. The coefficient of static friction for the rope on the pole is 0.35.
