What are the ground loads?

Air loads

Gust loads

Lift and drag

Loads acting due to aircraft motion on ground

Correct Answer : Loads acting due to aircraft motion on ground

Explanation : Loads that are acting due to aircraft motion on the ground is termed as ground loads. Air loads and gust loads are loads acting during the flight phase. Lift and drag are Aerodynamic forces acting on the aircraft. Lift is responsible for lifting the aircraft and drag is a resistive force.

The highest compression load which will not cause the elastic column buckling is called _________

euler load

divergence

newtonian fluid

bernoulli�s theorem

Correct Answer : Option (A) : euler load

Explanation : Euler load is defined as the highest compression load which will not cause the elastic column buckling. Euler load is also termed as critical load. Bernoulli’s theorem is used for fluids. Newtonian fluid are those fluids which follow the Newton’s law of viscosity.

Column is supported by pin at both the ends and has length of 10 unit. If radius of gyration is 3.16 unit then find slenderness ratio.

0.56

2.13

3.16

5.67

Correct Answer : Option (C) : 3.16

Explanation : Given, column is supported by pin at both the end.
Now, slenderness ratio = effective length/ radius of gyration = 10/3.16 = 3.16.

How do you define slenderness ratio?

Ratio of lift to drag

Ratio of Thrust to weight

Ratio of slender body width to the bluff body height

Ratio of column�s effective length to c/s radius of gyration

Correct Answer : Option (D) : Ratio of column�s effective length to c/s radius of gyration

Explanation : The ratio of column’s effective length to c/s radius of gyration can be termed as slenderness ratio. The effective length of the column is determined based on the end constraints such as pinned joints, fixed ends etc.
