Cars A and B are traveling respectively at the constant speeds of (vA)0 = 36 km/h and (vB)0 = 20 km/h on an ice-covered road. To avoid overtaking car B, the driver of car A applies his brakes so that his car decelerates at a constant rate of 0.14 ft/s2. Determine the distance d between the cars at which the driver of car A must apply his brakes to just avoid colliding with carB.
what is the minimum distance d at which the brakes must be applied to avoid a collision? Treat the train as a particle and assume that the railroad tracks are rectilinear and horizontal.
Determine the failure envelope and the non-failure region in the sigma_y - tau_xy plane using Tsai-Hill theory for the following cases
A hydraulic shear applies 2000 lb force to a wedge. It is used to shear plate steel to rough size. The shear has a 1/4 inch thick cutting blade with a 45 degree slope. What is the ideal mechanical advantage of the wedge?
Determine the natural frequencies of the system-For the baseline system and find a design that changes the ?rst two natural frequencies more than any of the previous slight modi?cations.
Estimate the Schmid Factor, which is used to convert the CRSS into a critical tensile 'yield' stress. Use the measured angle between the slip trace and the sample long axis
Steam at 15 bar and 350 degrees C is expanded through a 50% reaction turbine to a pressure of 0.14 bar. The stage efficiency is 80% for each stage and the reheat factor is 1.05.
Refrigerant 134a enters a heat exchanger in a steady state refrigeration system as saturated vapor at 0 °F and exits at 20 °F with no change in pressure.
Write a literature review and the title is "the effect of fluid cooling on the performance of building integrated photovoltaic thermal systems. Using some BIPVT prototypes measure their thermal and electrical output and dtermine their effectiveness"
The hull of a boat has a volume of 150 m3, and the total mass of the boat when empty is 8560 kg. Determine how much load this boat can carry without sinking (a) in a lake and (b) in seawater with specific gravity of 1.03.
How do I calculate isentropic efficiency of a steam turbine when I know the inlet and outlet conditions?
Bypass air exits at 600 m/s while combustion air exits at 1000 m/s. What is the thrust in kN of this engine?
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
