Engineering Mechanics In a screw jack, the effort required to lift the load is given by (where W = Load lifted, α = Helix angle, and φ = Angle of friction.) P = W cos (α + φ) P = W tan (α - φ) P = W tan (α + φ) P = W tan (φ - α) P = W cos (α + φ) P = W tan (α - φ) P = W tan (α + φ) P = W tan (φ - α) 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 = ΣV/ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣH/ΣV tanθ = ΣV/ΣH tanθ = √(ΣV + ΣH) tanθ = ΣV × ΣH tanθ = ΣH/ΣV ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called Newton's second law of motion Principle of conservation of momentum Newton's first law of motion Principle of conservation of energy Newton's second law of motion Principle of conservation of momentum Newton's first law of motion Principle of conservation of energy ANSWER DOWNLOAD EXAMIANS APP
