AIRCRAFT STRUCTURES -I-UNIT-1

A member under compression is called

• Strut

• Tie

• Beam

• Shaft

A member of the truss does not sustain

• tensile load

• compressive load

• bending load

• axial load

If a member of a truss is in tension, then what will be the direction of force that it will apply to the joints?

• Outward

• Inward

• Depends on case

• No force will be there

The vertical component of a force inclined through θ° is obtained by multiplying the force by

• sin θ

• cos θ

• tan θ

• sin θ cos θ
