Fatigue testing determines the response of a material to

Back

cyclic loads

Front

Bernoulli's principle is best described as

Back

where fluid velocity is high, pressure is low

Front

Jet engines are

Back

gas turbines

Front

Dynamic pressure is

Back

total pressure less static pressure

Front

Polymers may be described as

Back

organic macro-molecules

Front

Magnetic particle testing identifies cracks

Back

on surfaces of magnetic materials

Front

Identify the appropriate lift-to-drag ratio if an aircraft requires 1 500 kN of lift with an attendant drag of 100 kN.

Back

15 : 1

Front

For the aircraft illustrated, maintaining constant speed and level flight, calculate the drag and lift if the weight is 2.5 tonnes and the thrust is 45 kN.

Back

Drag = 45 kN, Lift = 25 kN

Front

In a hydraulic system, fluid is supplied under pressure to a mechanism transferring this force into mechanical movement by means of a: ram, wing flap, servo motor, linear actuator

Back

linear actuator

Front

Advanced fibre-composite materials exhibit their greatest mechanical strength when subjected to: compression, shear, tension, torsion.

Back

tension
