Car B is initially stationary and is struck by car A, which is moving with speed v. The mass of car B is pm, where m is the mass of car A and p is a positive constant. If the coefficient or restitution is e = 0.1, express the speeds υA and υB of the two cars at the end of the impact in terms of p and v. Evaluate your expressions for p = 0.5.
The probability that a new car battery functions for over 10,000 miles is .8, the probability that it functions for over 20,000 miles is .4, and the probability that it functions over 30,000 miles is .1. If a new battery is still working after 10,..
How would you structure a portion of an Aviation Safety program for a commercial airline or government agency. Briefly describe one or two safety problems and why it is a serious safety problem.
What is the difference between stiffness and flexibility matrix
The interior height of the cone is 3.60 in. The cone has an exterior radius of 1.25 in and an interior radius of 1.10 in. The scoop of ice cream sits on the cone's interior radius and extends into the cone some distance.
The velocity of flow toward the sphere along the longitudinal axis is found to be u = - U0 (I - r~/_xl), where r0 is the radius of the sphere and x the distance from its center.
The boom supports two vertical loads. Neglect the size of the collars D and B and the thickness of the boom, and compute the horizontal and vertical components of force at the pin A and the force in the cable CB. Set F1= 800 N and F2= 350 N.
The center of gravity of the crane is 10 ft from the pin, and the crane weighs 200 lb. What is the tension in the horizontal cable.
A thin-walled pipe, of diameter 4 in., is held stationary in a river flowing at 6 ft/s parallel to its axis. The pipe contains a sharp-edged orifice, of diameter 3 in., with a contraction coefficient of 0.60 based on the area.
If the design speed of a multilane highway is 60 mph, what is the minimum sight distance that should be provided on the road if (a) the road is horizontal and (b) the road has a maximum grade of 5%? Assume the perception/reaction time is 2.5 seconds...
A diving board of uniform cross-section is designed to deflect 6" under the weight of a 150 pound person standing on the end. With the recent trend towards obesity
An oedometer test on a clay soil gave the following results: Cc = 0.4, Ce = 0.08, OCR = 5. The thickness of the clay layer in the field is 2.6 m. The existing vertical effective stress at the mid-depth of the clay layer is 150 kPa. This vertical effe..
