The photograph shows two U.S. Coast Guard icebreakers in an ice field, and a simple model for an ice breaking operation. If the coefficients of static and kinetic friction for contact between the ship's bow and ice are 0.08 and 0.06, respectively, and if the ship produces a thrust of 10^6 lb, determine the normal and friction forces acting on each side of the ship's bow as it moves through the ice field with constant velocity. Assume the ship makes contact with the ice only on its bow, and neglect all forces between the ship's hull and water except for the thrust.
A tow truck is using a cable to pull a car up a 15 degree hill. If the car weighs 4000 lbs and the cable has a diameter of .75 inches, find the stress in the cable when the truck comes to a stop while on the hill.
create a visual, window-based program for multiplying two 3x3 matrices together. Create 18 text boxes for input and 9 text boxes or labels for output
A rectangular channel of width 12 ft has an upstream slope of 0.02 ft/ft and a downstream slope of 0.0005 ft/ft. Both reaches have lengths of 500 ft. The upstream reach has a Manning's roughness of 0.016 and the downstream reach has a roughness of..
A manometer of water reads a height of 20cm at a temperature of 15 degrees C. If the diameter of the manometer tube is 1mm, what is the static height reading
if you were asked to determine the mechanical properties of ametal by concucting a test, what type of test whould you use, and what data can you abtain from that test
A signal approach has 20 seconds of displayed green, 4 seconds of yellow, and 3 seconds of all red (assume typical start-up, lost time, and clearance time). The cycle length is 60 seconds.
A car is traveling at 30 mph on a good, dry pavement at sea level. The front-wheel-drive car has a drag coefficient of 0.35, a frontal area of 30 ft2 and a weight of 2500 lbs. The wheelbase is 120 inches and the center of gravity is 20 inches from..
What would the B/C ratio be if the light poles were twice as far apart as assumed above?
The ball at A is kicked such that theta=30 degrees. If it strikes the ground at B having coordinates x=15 ft, y= -9ft, determine the speed at which it is kicked and the speed at which it strikes the ground.
Calculate the minimum set-back distance required for a national highway of 4 lane divided carriageway having circular curve of radius of 350 m & design speed 100 km/hr.
q1. briefly explain the purpose of the international space station and list the name of all space agencies involved in
Write a MATLAB code that calculates the weight (forces due to gravity) in lbf on each planet of our solar system and earth's moon for probes/rovers which have a mass between 100 lbm and 300 lbm. Use increments of 20 lbm.
