Q7: The structure consists of a collar at B that is free to slide along a straight fixed bar AC. Mounted on the collar is a frictionless pulley, around which a cable supporting a 5 lb weight is wrapped. The collar is further supported by a bar BD. (a) If a = 0°, determine the force in bar BD needed to keep the system in equilibrium. (b) Determine the value of a, that will provide for the smallest force in bar BD, and determine the value of this force. E B 30° 5 lb

Choose correct answer: When the cylinder is cushioned at the end of the stroke, how does cushioning affect the piston's force? At the beginning of the stroke, cushioning increases the piston's force. At the beginning of the stroke, cushioning reduces the piston's force. At the end of the stroke, cushioning increases the piston's force. At the end of the stroke, cushioning reduces the piston's force.

Problem: Consider fully-developed flow of water through a 24-cm diameter tube. The water comes in at 20°C and exits at 40°C. The surface temperature of the tube is uniform at 60°C. The water flow has a mass flow rate of 0.24 kg/s. What is the average convection coefficient of the water flow? Solution: We have T, = 60°C, Tmi = 20°C, Tmo = 40°C, So, the bulk-mean temperature is Tm = 30°C. The appropriate properties are: u = 7.98 × 10-4 kg/ms; k = 0.615…

Part 2 Set up a spreadsheet solution to this problem. This will require that you derive one formula to express the relationship between the friction coefficient, the spring constant, and the spring compression; and a second formula to find the cost of using different slide and spring types. Set up your spreadsheet as shown below. You can fill in the "Acceptable?" column manually, rather than using a formula.
