The 2-kg slider fits loosely in the smooth slot of the disk, which rotates about a vertical axis through point O. The slider is free to move slightly along the slot before one of the wires becomes taut. If the disk starts from rest at time t = 0 and has a constant clockwise angular acceleration of 0.5 red/s2 plot the tensions in wires 1 and 2 and the magnitude N of the force normal to the slot as functions of time t for the interval ≤ t ≤ 5 s.
A point source with effective stack height of 50 m emits 80 g/s of on a clear summer day with surface winds at 4 m/s. Winds at 50 m are 5 m/s. An inversion layer starts at an elevation of 250 m.
Suppose that a water treatment plant has a Parshall Flume with a 4 ft wide throat. a) If the upstream depth of the water (ha) is 1 ft and the depth of the water in the throat section (hb) is 0.65 ft, what is the flow rate in gpm
A rear-wheel-drive car 2600 lb, has an 80-inch wheelbase, a center of gravity 20 inches above the road surface and 30 inches behind the front axle, a drivetrain efficiency of 85%, 14-inch-radius wheels,
Conduct a powder factor design for the following conditions: -Rock is iron ore; density is 5370 lb/cubic yards -Rock swells 60% from in situ when broken -Bench height is 45ft -Drill hole diameter is 12.25 inches
Compare your results to those obtained by combining the ln KP values for the two equilibrium reactions CO2 = CO + O2 and H2O = H2 +O2 given in Table A-28. 0031
If the rod is snugly fitted against two immovablenonconducting walls at a temperature of 15oC and thenheated uniformly to at 115oC, what is its length at115oC? If the modulus of elasticity of steel is 207 GPa,what is the stress induced in the bar? Is..
The three hinged arch is composed of segments of a circle. Support points A and D are not at the same level.Determine: (a) the horizontal and vertical components of reaction at A and D.
The stream hts a stationary splitter, such that half of the flow is diverted upward at 45o. and the other half is directed downward, and both streams have a final speed of 18ft/s.
What effect does removing 70-100 sieve fraction have on the head-loss characteristics and on the depth of expanded bed and Comment on the differences and likely reasons for the differences.
Water is flowing in a 6-cm diameter pipe at 20 m/s at 10?C. If the pipe enlarges to a diameter of 12-cm, calculate the reduced velocity. Also, calculate the mass flux rate and the flow rate.
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
If you have 10 kips acting downward on a foundation and footing, 4 feet long, with uniformly distributed load acting up ward of 2.5 k/ft (soil) also 4 ft long. what are the reactions, shear forces, and bending moments at the tree critical points?
