Which of the following is an equation of linear motion?(where, u and v = Initial and final velocity of the body, a = Acceleration of the body, and s = Displacement of the body in time t seconds.)

Engineering Mechanics
Which of the following is an equation of linear motion?(where, u and v = Initial and final velocity of the body, a = Acceleration of the body, and s = Displacement of the body in time t seconds.)

v = u + a.t

v2 = u2 + 2a.s

s = u.t + ½ a.t2

All of these

v = u + a.t

v2 = u2 + 2a.s

s = u.t + ½ a.t2

All of these

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

IP = IG + Ah2

IP = IG / Ah2

IP = Ah2 / IG

IP = IG - Ah2

IP = IG + Ah2

IP = IG / Ah2

IP = Ah2 / IG

IP = IG - Ah2

Engineering Mechanics
A body of weight 'W' is required to move up on rough inclined plane whose angle of inclination with the horizontal is 'α'. The effort applied parallel to the plane is given by (where μ = tanφ = Coefficient of friction between the plane and the body.)

P = W (cosα + μsinα)

P = W tanα

P = W (sinα + μcosα)

P = W tan (α + φ)

P = W (cosα + μsinα)

P = W tanα

P = W (sinα + μcosα)

P = W tan (α + φ)
