Question 14

what do you call any non-rigid body that changes its natural shape or form when an external force acts upon it?

Answer 14

deformation

Question 15

T OR F

Can deformation differs depending on the interfering external force?

Answer 15

true

Question 16

what is the tendency of a body to return to its original state after deformation?

Answer 16

elasticity

Question 17

what is the propensity of a body to remain deformed even after the load is removed?

Answer 17

plasticity

Question 18

what condition occurs when elastic boundaries are exceeded?

Answer 18

plastic conditions

Question 19

these are derived from the effects of externally applied loads acting on the body being analyzed

Answer 19

actual forces, stresses, moments

Question 20

these are computed from the structural properties of the member in question that speaks of the prescribed capacity of the member

Answer 20

allowable or working forces, stresses, moments

Question 21

T OR F

a body is not capable of resisting the applied load and the effects of which should be within the safe and acceptable range

Answer 21

false

Question 22

T OR F

allowable force (capacity) > actual force (applied load)

Answer 22

true
