A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. Bearing life is determined by load, temperature, maintenance, lubrication, material defects, contamination, handling, installation and other factors. What strategies are you going to make to lessen the effects of the mentioned factors?

Describe working and environmental conditions that lead to failure for a product made from material from each of the four material categories.

Q1: How do your results for μs and μk compare to literature values for dry metal on plastic? Cite what you compared to. Do they agree with the literature within error? If not, discuss any systematics that could have contributed to the discrepancy. Q2:  Is the force of static friction constant as the incline rises? Explain your answer. My Us value is 0.4452, and Uk value is 0.33

Select a conventional ICE (Internal Combustion Engine) passenger car from the market. Convert the ICE powertrain to an electric powertrain using the structural and performance parameters of the vehicle by calculating the electric motor shaft power, torque and speed, sketching the required graphs of the vehicle performance, selecting a proper gearbox ratio, analysing the gradeability performance of the car, selecting a battery pack and define battery voltage, current and energy capacity (Give thereasons of your selection), and defining the performance and energy consumption of the car for a specific drive cycle (calculate the cost of the drive considering the price of electricity too).
