However, if it goes through this critical value with enough speed, the amplitude of vibration will not increase to dangerous levels. The critical angular speed is also known as whirl. The stable condition occurs when (1.42)ϕ̇=ω Integrating this equation: (1.43)ϕ=ωt−φ Show more...
Physics.defaultMaxAngularSpeed public static float defaultMaxAngularSpeed ; 説明 Default maximum angular speed of the dynamic Rigidbody, in radians (default 50). Controls the maximum angualr speed of the dynamic Rigidbody, measured in radians. The angular speed limit can also be modified with ...
In everyday discourse, "speed" and "velocity" are often used interchangeably. In physics, however, these terms have specific and distinct meanings. "Speed" is the rate of displacement of an object in space, and it is given only by a number with specific units (often in meters per second ...
aThe reason is that the driver’s speed sense of objects on the road is not the sense the driver feels the physics quantity of speed, but the sense that the driver feels the angular velocity that is between eyes and the object 原因是对象司机的速度感觉在路不是司机感觉速度的物理数量的感觉,...
Because the angular momentum L of a rigid body is the sum of angular momenta of the individual particles that comprise the system and because any torque applied to a particle in the system is a torque applied to the system, Equation (7-30),∑τ = dL/dt, applies to rigid bodies. Show...
an analysis is conducted on the scenario where one of the guy-wires breaks. The mast would then rotate about its base opposite the broken wire. Determine the tip speed of the mast as a function of its tilt angle θ relative to the vertical by applying the rotational dynamics equationdL...
Two cases are examined: (1) the point of intersection of the plate with the free fluid surface moves along this surface faster than the speed of sound in the fluid, and (2) below the speed of sound. Numerical results are given. 展开 关键词:...
NC: number of cycles; TNC: time to complete NC cycles; LNC: distance covered in NC cycles; LC: gait cycle length; TC: time spent doing a full cycle; SC: speed. Figure 4 shows the variation of the angle at the tibiotalar joint (θAθA) during the gait cycle for each heel ...
circle. The angular momentum depends on the mass and velocity of the body, and on the radius of the circle that it is moving along. Because the velocity of a body moving in a circle is always changing (since velocity is speed and direction), its angular momentum is also always changing....
The discovery of optical transverse orbital angular momentum (OAM) has broadened our understanding of light and is expected to promote optics and other physics. However, some fundamental questions concerning the nature of such OAM remain, particularly wh
