In moment summation, the moment of the resultant force about point O is equal to the sum of

Two trains 'A' and 'B' are moving on parallel tracks in opposite directions. The velocity of 'A' is twice that of 'B'. They take 18 seconds to cross each other. What are the velocities of trains A and B ? Take length of train A as 240 m and that of B as 300 m.

Experiments with sliding block indicate that the magnitude of the kinetic friction force is __________ to the magnitude of the resultant normal  force.

_________ states that the algebraic sum of moments of two unequal forces about any point in their plane is equal to the moment of their resultant about that point

In dry friction, the frictional force acts to the contacting surfaces in a direction opposed to the motion or tendency for motion of one surface relative to another.

A surveyor measured the distance between two points (A and B) on the plan drawn to a scale of 1 cm = 30 m and the result was 512 m. Later, however, he discovered that he used a scale of 1 cm = 10 m. Find the true distance between points A and B
