## Applied Mechanics and Graphic Statics A ball which is thrown upwards, returns to the ground describing a parabolic path during its flight

Kinetic energy of the ball remains constant
Vertical component of velocity remains constant
Horizontal component of velocity remains constant
Speed of the ball remains constant

## Applied Mechanics and Graphic Statics Free body diagram is an

None of these
Isolated joint with all the forces, internal as well as external, acting on it
Isolated joint with internal forces acting on it
Isolated joint with only body forces acting on it

## Applied Mechanics and Graphic Statics If two forces are in equilibrium, then the forces must(i) Be equal in magnitude(ii) Be opposite in sense(iii) Act along the same line

(i) and (iii)
(i) and (ii)
All (i), (ii) and (iii)
Only (i)
