1.Sometimes driving your car on a hot day, you may encounter a problem with the fuel pump called pump cavitation. What is happening to the gasoline? How does this affect the operation of the pump?
2.A satellite is launched 600 km from the surface of the earth, with an initial velocity of 8333.3 m./s, acting parallel to the tangent of the surface of the earth. Assuming the radius of the earth to be 6378 km and that is 5.976 * 10^6 kg, determine the eccentricity of the orbit.
Design a cord (design the constants k and ) so the cord stretches 2.5 times the unstretched length, and the acceleration of the jumper doesn't exceed 3g, and the cord has zero stiffness at the bottom of a 400ft drop.
If the coefficient of static friction between the cord and the fixed peg at B is fs =0.25, determine the minimum weight of the bucket that will prevent the block from sliding down the incline.
A rectangular tube has an outside dimensions that are 2in wide and 4in deep and a wall thickness of 0.25in. The tube is acted on by a bending moment of 12,000lb-in.
What force is necessary to lift a thin 25-mm diameter ring out of :
A vertical curve is to connect two tangents that intersect at station 50+00 and the elevation 500.00ft. The back tangent gradient is -4 percent, the forward tangent gradient is 2 percent, and the elevation of the curve at station 48+50 must equal ..
Consider the flow field where angular velocity w is equal to 2pi rad/s ( a physical frequency of 1 Hz). Is this flow field compressible or incompressible
At standard pressure, 14.7 psi absolute, it holds 0.5-slug of water; rho = 1.94 slug/ft^3. For K = 300,000 psi, when it is filled, how many slugs of water must be added to increase the pressure to 10,000 psi
Determine the discharge of a trapezoidal concrete channel section with a bottom width of 4 ft and side slopes of 2:1. The depth of flow is 5 ft and the channel slope is 0.5%
While washing up Grandma's old aluminum cooking pot I noticed that it would just barely touch the bottom of the sink if I added 2.5 cups of water to it. The pot is 3.5 in high and 9.5 in diameter. Thickness of aluminum is 3/16 in.
The defender had a first cost of $300,000, but its market value now is only $100,000. It has chargeable expenses of $120,000 per year and no expected salvage value. To simplify calculations, assume that SL depreciation was charged at $60,000 per y..
Let E be an unsorted set of n segments that are the edges of a convex polygon. Describe an O(nlogn) algorithm that computes from E a list containing all vertices of the polygon, sorted in clockwise order.
