In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
Approximate force applied by the motors of a Tesla Model S during maximal acceleration [22] 25.5 to 34.5 kN The estimated bite force of a large 6.7 m (22 ft) adult saltwater crocodile [23] 10 5 N 100 kN The average force applied by seatbelt and airbag to a restrained passenger in a car which hits a stationary barrier at 100 km/h [24] 569 kN
Calculate the current value of the future company value by multiplying the future business value with the discount factor. This is known as the time value of money. Example: VirusControl multiplies their future company value with the discount factor: 44,300,000 * 0.1316 = 5,829,880 The company or equity value of VirusControl: €5.83 million
The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...
A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load.
In analytical mechanics (particularly Lagrangian mechanics), generalized forces are conjugate to generalized coordinates. They are obtained from the applied forces F i , i = 1, …, n , acting on a system that has its configuration defined in terms of generalized coordinates.
D'Alembert's principle generalizes the principle of virtual work from static to dynamical systems by introducing forces of inertia which, when added to the applied forces in a system, result in dynamic equilibrium. [1] [2] D'Alembert's principle can be applied in cases of kinematic constraints that depend on velocities.
In physics, and in particular in biomechanics, the ground reaction force (GRF) is the force exerted by the ground on a body in contact with it. [1] For example, a person standing motionless on the ground exerts a contact force on it (equal to the person's weight) and at the same time an equal and opposite ground reaction force is exerted by the ground on the person.
