Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. Davits can also be used as man-overboard safety devices to retrieve personnel from the water. The lifeboat davit has falls (now made of wire, historically of manila rope) that are used to lower the lifeboat into the water.
Method 1 of 2: Using Force and the Moment Arm. 1. Identify the forces exerted on the body and their corresponding moment arms. If the force is not perpendicular to the moment arm being considered (i.e. it's mounted at an angle) you may need to find its components using trigonometric functions, such as sine or cosine.ethod 1 of 2: Using Force and the Moment Arm. 1.
