It is measured with the SI unit of newtons and represented by the symbol F. 例句与用法 1. He forced a laugh to his shaking lips .他颤抖的两唇发出了一声干笑。 2. The company was forced to pass its dividend .该公司被迫到期不分红。 3. The viscous drags is equal to the resultant ...
Force:A description of an interaction that causes a change in an object's motion. It can also be represented by the symbolF. The Newton:The unit of force within the International system of units (SI). It can also be represented by the symbolN. Contact forces:Forces which take place when...
strength of the electric field between two charged objects depends on the strength of the charges of the objects and on the distance between them. The greater the charges are, the stronger the field is, and the greater the distance between the charged objects is, the weaker the field is....
Since the IPMC is not structurally homogeneous, its Young’s modulus cannot be defined strictly speaking. Nevertheless, the moment of inertia of the area of the IPMC must basically be constant during bending. Hence, the bending stiffness can be approximately represented by 𝐸 𝐼E¯I where ...
You can see that sf.Rot2 is represented internally by a complex number (𝑅𝑟𝑒, 𝑅𝑖𝑚) and we can study how it rotates the landmark 𝐿. For exploration purposes, let's take the jacobian of the body-frame landmark with respect to the tangent space of the Pose2, parameteriz...
The optimal trajectory should satisfy the appointed terminal constraints, which are represented by Eq. (7.51). In this chapter, the operation robot should arrive the terminal point, which must match the position and velocity relative to the target at the arrival time tf, which can be expressed ...
Another standard of mass used on the Continent is the kilogramme, represented by a cylinder of platinum-iridium kept in France. The gravitational force exerted on this mass is called the kilogramme-force. The relationship between the pound-force and the kilogramme-force is 1 pound-force (lbf)=...

that is, an increase in speed of 10 times, say from 10 to 100 revolutions per minute, increases the centrifugal force by a factor of 100. Centrifugal force is expressed as a multiple ofg, the symbol for normal gravitational force (strictly speaking, the acceleration due to gravity). Centrif...
Conservative forces (gravity and centrifugal) are represented by an averaged value of gravitational acceleration (g) and deviations from the local geoid (z). Nonconservative forces u˙, heating, and irreversible and diffusive processes (Ṡ, Θ˙, c˙) are included but not specified. The ...
