Determine the required height h of the roller coaster so that when it is essentially at rest at the crest of the hill it will reach a speed v= 100km/hr when it comes to the bottom.Also,what should be the minimum radius of curvature p for the track at B so that the passengers do not experience a normal force greater than kmg?neglect the size of the car and passengers.Take k=4.
The dimension h is to be determined so that a worker can comfortably slide boxes weighing up to 100lb up and downa frictionless incline. If the worker can apply a 50lb horizontal force to the box
Determine the horizontal component of reaction that the pin A exerts on the two-member frame. Set F = 500 (Find Ax) Determine the vertical component of reaction that the pin A exerts on the two-member frame.
A concrete cylinder of height 8 inches and diameter of 4 inches was tested in the lab. The maximum compressive force was found to be 150,000 lbs and a tensile force of 25000 lbs.
A power plant operates at steady-state. It receives energy from a hot source (combustion of fuel) at a temperature of 420 oC. The plant discharges this energy to a nearby river that acts as a cold source.
The discharge from the Renenutet sugar beet plant causes the DO at the critical point to fall to 4.0 mg/L. The Meskhenet Stream has a negligible BOD and the initial deficit after the river and wastewater have mixed is zero
The C-S-H gel can come in a variety of chemical structure forms. If it has a cement notation form of C3 S2 H8, what is the periodic table form of this C-S-H gel. What would be the balanced equations for C3 S and C2 S when hydrated into this form
Develop an estimate of the volumetric flow rate of air that will be required for aeration of the mixed liquor in an activated sludge system.For this calculation, assume that the (ultimate) CBOD is 200 mg/L and (ultimate) NBOD is 50 mg/L.
Discuss whether shoe A (leather) or shoe B (synthetic) is better for the environment based on the data in the table below. Is it possible to weight one aspect (air, water, land pollution or solid waste) as being more important than anothe
In magnetic tape recording, the tape is subjected to tension while it is guided along its path. Tension in the tape causes elastic deformation that results in slight changes in length of the domains on which information is stored.
An April 2009 survey of 2253 American adults conducted by the Pew Research Center's Internet & American Life Project revealed that 1262 of the respondents had at some point used wireless means for online access.
What is the effective stress 25 feet deep if the specific weight of the dry soil (dry unit weight) is 120 pcf and the water table is 12 feet deep
