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.) All of these s = u.t + ½ a.t2 v = u + a.t v2 = u2 + 2a.s All of these s = u.t + ½ a.t2 v = u + a.t v2 = u2 + 2a.s ANSWER DOWNLOAD EXAMIANS APP
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 (sinα + μcosα) P = W tanα P = W (cosα + μsinα) P = W tan (α + φ) P = W (sinα + μcosα) P = W tanα P = W (cosα + μsinα) P = W tan (α + φ) ANSWER DOWNLOAD EXAMIANS APP
