2. resultant的意思 2. The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero. 平衡条件物体或体系静止或处于非加速运动的状态,在这种状态下所有力的和为零,所有轴...
Moments are the forces generated by angular momentum. Momentum is mass multiplied by velocity and will be discussed further in Section 1.2.2. An easy example to give is that of two children of different weights sitting at the opposite ends of a seesaw, trying to balance each other. If the...
angle ___ Vector Analysis When determining the resultant force of two or more forces, we have to first find the total of the horizontal and vertical components of the forces, {eq}R_x {/eq} and {eq}R_y {/eq}. If we a...

Resultant Force: When there are many forces acting on a plane, or in three-dimensional space, we can combine the effects of all the force into a resulting force, calledresultant force. This process is called the composition of forces
In Image 3, parallelogram ABCD has vector forces along sides AB and AC, which are at an angle of 33 degrees, or σ. The diagonal line AC is equal to the resultant force. The length of this line can be calculated using the right triangle CMD. Using the Pythagorean theorem, side AC is...
find the algebraic sum of the ponent forces in the X and Y directions separately. Finally use Pythagous Theorem and trigonometry method to determine the magnitude and direction of the resultant force. Example given force A of magnitude 10 N at angle 30 degrees above the X-axis. ...
