WebApr 2, 2024 · How F=mv^2/r? Please explain. Asked by bhavana147 02 Apr, 2024, 09:16: AM Expert Answer Let us consider a particle of mass 'm' be moving in a circle of radius 'r' with a constant speed 'v'. Consider that the point is at A at any instant and then at B after a short time 't'. Thus, AB = vt. The velocity at A is along the tangent AL and at B is ... WebQuestion: A mechanical speed control system works on the basis of centrifugal force, which is related to angular velocity through the formula F = mrw2 where F is the force, mis the mass of the rotating weights, r is the radius of rotation, and w is the angular velocity of the system. The following values are measured to determine w:r = 200.02 mm, m = 100 0,5 …
向心力的公式是F=(mv^2)r和F=mrw^2吗? - 雨露学习互助
Web解:以滑块B为研究对象,当φ=t时,受力如图9-2b所示。由于不计连杆质量,连杆应受平衡力系作用,AB为二力杆,它对滑块B的力F沿AB方向。写出滑块沿x轴的运动微分方程ma, = -Fcos B FFN 由运动方程,可以求得BBd'x xdt = -ro cos + Acos )(b)wt=0时,a,=-rw2(1+),且B=0,得F=mrw2(1+)AB杆受拉力。 legal term for bait and switch
