find magnitude of the resultant force, if 30N, 40N, 50N and 60N forces are acting along the line joining the centr of a square to its vertices

Calculate the power required to accelerate a 1150 kg car from rest to a final velocity of 30 m/s up a 100 m long uphill road with a slope of 30 degrees from horizontal over a time of 12 seconds. Disregard friction, air drag, and rolling resistance.

Braking is when you squeeze the brake pedal until just before the wheels lock the ease off the pedal then squeeze again repeating until you've reduced your speed enough. hij

Air at 1 atm enters a thin-walled (5-mm diameter) long tube (2 m) at an inlet temperature of 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is 140 * 10-6 kg/s.

What minimum radius of curvature may be designed for safe operation of vehicles at 70 mi/hr if the maximum rate of superelevation (e) is 6% and the maximum coefficient of side friction (f) is 0.10?

Fuel cells have been proposed for use in cars and for power generation as part of a hydrogen economy. They offer the advantages of higher efficiency and cleaner fuel with insignificant pollutants.

Technician A says that clutch slippage can be a result of excessively strong pressure plate spring (s). Technician B says that when replacing the friction disc, it is good practice to also replace the pressure plate. Who is correct?
