You are given that a piece of rope is 90.5 ft long. The distance between the poles holding the rope is 90 ft. Find the tensions in both sides of the rope for someone walking across the rope and the deflection for every 0.5 ft up to 45 ft. much like the problem in our book(2.C7, Vector mechanics for engineers:statics). Setting the problem up to find the deflection as the person walks across the rope.
The profile of the bridge and tunnel. Devise a vertical alignment to connect the tunnel and bridge by determining the highest common design speed for the sag and crest (equal tangent) vertical curves needed.
a closed tank contains two straified non misicble fluid layers and compressed air. the fluid of the tank is saline water (relative density 1.036) with a total depth of 3.5m. the top fluid layer is oil (relative density of 08.2) with a depth of 0.6..
Determine the design compressive strength for a pinned ended HSS 8x8x3/8 column of ASTM A500, grade B steel with an unbraced length of 35ft
how far back from the front axle would the center of gravity have to be to ensure that the maximum tractive effort developed for front- and rear- wheel-drive options is equal (assume that all other variables are unchanged)
A 12 foot W14 X 22 column with pinned ends is axially loaded. The max load it can carry is 34 ksi. Determine (a) Euler buckling stress, (b) Euler buckling load. (A = 6.49 in^2) (ry = 1.04 in) (Iy = 7.00 in^4)
An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
What are two types of variables that can be used for values that are less than 128, and describe what is the difference between the variables, how to declare them, and the memory allocated and the numerical range for both.
What is the Federal Express philosophy toward quality? What specific elements/actions has FedEx implemented in its quality improvement history?
to achive a specific level of disinfection a water treatment plant operator determines the" Ct" value 180mg min/l is necessary with units for disinfectant concentration C in mg/l and disinfectant contact time t in minutes
Two factories are manufacturing and supplying a single type of good to four warehouses. The factories can produce a1, and a2 units of the good each month, and the warehouses need b1, b2, b3, and b4 units each month
The distance between the piston and the cylinder is .0011 inch. If the piston decelerates at 1.85 ft/s^2, when the speed is 19.5 ft/s. What is the viscosity of the oil. cylinder is 6 in high and 5 in long.
A fluid film 0.1 mm thick separates solid and surface. The fluid viscosity is 0.04 N*sec/m^2. Assuming the velocity distribution in the film is linear, find the terminal velocity of the block. The area of the cube in contact with the film is 0.25 ..
