Answer:
1. a) True
2. a) True
3. a) Four-wheel anti-lock brakes
Explanation:
1. True
When a wheel skids, there is less traction with the road and the vehicle is out of the driver's control
Breaks that have ABS are prevented from functioning fully in a situation where the contact between the tire and the road patch is broken and the tire is able to skid. Once the tire regains and maintains proper contact with the road surface such that the skidding has ceased, the full functionality of the brakes are restored, enabling the moving vehicle to stop faster and the steering to remain operational
2. True
A vehicle that has a standard Electronic Stability Control, ESC, is less likely to rollover. According to a University of Michigan Transport Research Institute study, SUVs equipped with an ESC are 73% less likely to have fatal rollover crashes
3. a) Four-wheel anti-lock brakes
The four-wheel anti-lock *four-wheel ABS) brakes works such that each wheel has a sensor through which if is detected that the wheel is about to lock, the ABS, ESC releases the break pad on the wheel such that the wheel keeps spinning
Answer:
The volume flow rate necessary to keep the temperature of the ethanol in the pipe below its flashpoint should be greater than 1.574m^3/s
Explanation:
Q = MCp(T2 - T1)
Q (quantity of heat) = Power (P) × time (t)
Density (D) = Mass (M)/Volume (V)
M = DV
Therefore, Pt = DVCp(T2 - T1)
V/t (volume flow rate) = P/DCp(T2 - T1)
P = 20kW = 20×1000W = 20,000W, D(rho) = 789kg/m^3, Cp = 2.44J/kgK, T2 = 16.6°C = 16.6+273K = 289.6K, T1 = 10°C = 10+273K = 283K
Volume flow rate = 20,000/789×2.44(289.6-283) = 20,000/789×2.44×6.6 = 1.574m^3/s (this is the volume flow rate at the flashpoint temperature)
The volume flow rate necessary to keep the ethanol below its flashpoint temperature should be greater than 1.574m^3/s
Answer: True
Explanation:Typical metals have a property of ductility and malleability that is metals can be drawn into wires or any other shape by beating or stretching the metal by putting the tensile strength or shear strength that pulls them apart . But while compression the metals are squeezed together which affects the hardness of a metal and they are not able to bear the compression force well and thus cannot show elastic-plastic behavior while compression .Therefore the statement given is true typical metals show elastic-plastic behavior in tension and shear but not in compression.
