if the rolling resistance is 1/100 of the weight of the car, determine the compression of each spring when the car is momentarily brought to rest spring 1 500kN/m spring 2 300kN/m and distance between springs and car 30m
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
The river channel itself is 20m wide and flow depth is 5m and the sandy bottom has an n=0.02, the left bank is 40m wide and the flow depth is 0.5m, while the right bank is 100m wide with a flow depth of 1m.
A sample of undisturbed soil has a dry weight of 10 lb and volumen of 1 ft^3. If the specific gravity of the soil solids is 2.65, determine the void ratio and the porosity.
4. Determine the values for the Energy Grade Line and the Hydraulic Grade Line for the tank and pipe system of problem 3. Plot the EGL and HGL.
Two identical spheres of radius 8 in . and weighing 2 lb on the surface of the earth are placed in contact. find the gravitational attraction between them .
The air in a room has a dry-bulb temperature of 80°F and a wet-bulb temperature of 65°F.
A building is located 19 ft from the centerline of the inside lane of a curved section of highway whose radius is 400 ft. The road is level and e = 10. Determine the posted speed limit (to the nearest 5 mph) considering the following conditions:
On your first trip to Planet X you happen to take along a 165 g mass, a 40 cm long spring, a meter stick, and a stopwatch. You're curious about the free-fall acceleration on Planet X, where ordinary tasks seem easier than on earth
The combined weight of a bicycle and its rider is 190 lbs, and when the rider is on the bike, their frontal area is 5.4 square feet, with a drag coefficient of 1.2. The coefficient of rolling resistance can be taken to be a constant for all speeds
scenario this is a real case project client is considering building a four story dual usage flats suitable for both
A galvanized iron pipe with a roughness height (e) of 5x10-6 m with a diameter (D) of 0.05 m and a length (L) of 100 m carries a discharge (Q) of 0.003 m3/s. Calculate the head loss (hL).
