## Applied Mechanics and Graphic Statics A bullet weighing 10 gm moves with a velocity of l km/sec. Its kinetic energy is(i) 5000 Nm(ii) 5000 kg.m(iii) 5000 J

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

## Applied Mechanics and Graphic Statics On a ladder resisting on a smooth ground and leaning against a rough vertical wall, the force of friction acts

Upwards at its upper end
Away from the wall at its upper end
Towards the wall at its upper end
Downwards at its upper end

## Applied Mechanics and Graphic Statics The torque produced by a force depends oni. the magnitude of the forceii. the direction of the forceiii. the point of application of the force relative to originThe correct answer is

both (i) and (iii)
both (i) and (ii)
all (i), (ii) and (iii)
only (i)

y = c cosh ψ
y = c cosh x/c
S = c tan ψ
y = c sinh ψ

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