Engineering Mechanics
The time of flight (t) of a projectile on an upward inclined plane is(where u = Velocity of projection, α = Angle of projection, and β = Inclination of the plane with the horizontal.)

t = 2u sin (α - β)/g cos β

t = g cos β/2u sin (α + β)

t = g cos β/2u sin (α - β)

t = 2u sin (α + β)/g cos β

t = 2u sin (α - β)/g cos β

t = g cos β/2u sin (α + β)

t = g cos β/2u sin (α - β)

t = 2u sin (α + β)/g cos β

The moment of a force

Is the turning effect produced by a force, on the body, on which it acts

Is equal to twice the area of the triangle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken

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)
