Engineering Mechanics If a number of forces are acting at a point, their resultant will be inclined at an angle 'θ' with the horizontal, such that tanθ = ΣV × ΣH tanθ = ΣV/ΣH tanθ = ΣH/ΣV tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣV/ΣH tanθ = ΣH/ΣV tanθ = √(ΣV + ΣH) ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The resultant of the two forces ‘P’ and ‘Q’ is ‘R’. If ‘Q’ is doubled, the new resultant is perpendicular to ‘P’. Then P = Q Q = R Q = 2R None of the listed here P = Q Q = R Q = 2R None of the listed here ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The time of flight (t) of a projectile on a horizontal plane is given by t = 2u. tanα/g t = 2u/g.sinα t = 2u. sinα/g t = 2u. cosα/g t = 2u. tanα/g t = 2u/g.sinα t = 2u. sinα/g t = 2u. cosα/g ANSWER DOWNLOAD EXAMIANS APP
