  • Question 1/10
    4 / -1
    Weights 2, 3, 4 and 5 lbs are suspended from a uniform lever 6 ft long at distances of 1, 2, 3 and 4 ft from one end. If the weight of the lever is 11 lbs, then the distance of the point at which it will balance from this end is
  • Question 2/10
    4 / -1
    If the line of action of the resultant of two forces P and Q divides the angle between them in the ratio 1 : 2, then the magnitude of the resultant is
  • Question 3/10
    4 / -1
    P and Q are like parallel forces. If P is moved parallel to itself through a distance x, then the resultant of P and Q moves through a distance

  • Question 6/10
    4 / -1
    A beam whose centre of gravity divides it into two portions a and b is placed inside a smooth horizontal sphere. If θ be its inclination to the horizon in the position of equilibrium and 2α be the angle subtended by the beam at the centre of the sphere, then
  • Question 7/10
    4 / -1
    The resultant of two forces P and Q is R. If Q is doubled, R is doubled and if Q is reversed, R is again doubled. Ifthe ratio P2 : Q2: R2 = 2 : 3 : x, then x is equal to
  • Question 8/10
    4 / -1
    The resultant of P and Q is R. If P is reversed, Q remaining the same, the resultant becomes R\'. If R is perpendicular to R\', then
