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 = 2R Q = R None of the listed here P = Q Q = 2R Q = R None of the listed here ANSWER DOWNLOAD EXAMIANS APP
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 = ΣH/ΣV tanθ = ΣV × ΣH tanθ = ΣV/ΣH tanθ = √(ΣV + ΣH) tanθ = ΣH/ΣV tanθ = ΣV × ΣH tanθ = ΣV/ΣH tanθ = √(ΣV + ΣH) ANSWER DOWNLOAD EXAMIANS APP
