If an aircraft engine develops a forward force of 175,550 Newtons on the aircraft, what is...
(10 pts) An aircraft with a prop-driven 100 hp engine is flying at a speed of 200 ft/s at sea level. If the propeller generates 200 lb of thrust, determine the prop efficiency.
A jet aircraft with mass of 631,405.4 kilograms is flying straight downward. At an instant the plane's engine is producing an downward thrust (force) of 3,329,281.8 Newtons and air resistance is exerting a force of 714,785.5 Newtons upward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "down" as positive.
An engine develops 350 N m of torque at 3300 rev/min. Find the power developed by the engine.
An automobile engine develops a torque of 250 Nm at 3500 RPM. What is the power of the engine?
The riders push on the mower with a constant force of 50 Newtons for an hour. Using v = 0.40 m/sec, they push the mower a distance of how many meters? Also- they do work in how many joules?
A jet aircraft with a mass of 4,475 kg has an engine that exerts a force (thrust) equal to 60,200 N. (a) What is the jet's acceleration? (Give the magnitude.) (b)What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.) (c) How far does the jet travel during the 7 s?
A 150 kg rocket is launched at a 40 degree angle. The engine provides a force of 2000 newtons. The coefficient of kinetic friction is 0.2. The end of the ramp is 5 m high. What is the average operating power rating of the engine? What is the engine's power output the instant it leaves the ramp?
A jet aircraft with a mass of 4,675 kg has an engine that exerts a force (thrust) equal to 59,500 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s2 (b)What is the jet's speed after it accelerates for 9 s? (Assume it starts from rest.) m/s (c) How far does the jet travel during the 9 s? m
. A turbofan aircraft engine is flying at 720 km/h at an altitude of 6100 m, where the ambient conditions are 50 kPa and -12°C (a negative value). The pressure ratio across the compressor is 13, and the turbine inlet temperature (TIT) is 1330 K. Assuming ideal operation for all components and constant specific heats for the air at room temperature (cold air model). (a) Sketch the T-s diagram of the cycle, and determine: (b) The Mach number of the...
A solid 1.25 in. diameter shaft is used in an aircraft engine to transmit 140 hp at 2930 rpm to a propeller that develops a thrust of 1700 lb. Determine the magnitudes of the principal stresses and the maximum shear stress at any point on the outside surface of the shaft. Enter the principal stresses at any point on the outside surface of the shaft. Use the sign convention that a tension normal stress is positive and a compression normal...
