Static equilibrium and the requirements of this principle Lab Report

Static equilibrium and the requirements of this principle - Lab Report Example This research will begin with the statement that the principle of moments states that when a force (F) is applied to an object that can turn around a pivot when acted on by forces, the turning effect of the body is equivalent to the moment (M) of the force. The moment equals the force multiplied by the perpendicular distance (d) from the pivot. This means that the distance increases as the force decrease. The principle of moments has various practical uses in real life situations such as using a hammer to unscrew a nail, balancing objects around their pivots and among others. In regard to the principle of moments, â€Å"the sum of the clockwise moments about any point must be equal the sum of the anticlockwise moments about that point† for a body to be in equilibrium. This illustrates that the body will attain static equilibrium, as long as the product of the force and the perpendicular distance on either side of the pivot is the same. The illustration below strives to justify the concept of the principle of the moment: M = F Ãâ€" d †¦Ã¢â‚¬ ¦.equation 1  Ã‚  Ã‚   Where F is the force of the load and is measured in Newton (N), d is the distance from the pivot and is measured in meter (m), and M is the moment given by the product of force and distance. It is measured in Nm. The system balances because its clockwise moment and anticlockwise moment are equal. A body is said to be in static equilibrium when it is in a state of rest, that is, no motion.
