Looks to me like they all come to that same answer. I was confident the given answer was wrong because if you ignore the opposing torque from friction then you get g/4r, as you did in the OP. Bringing in an opposing torque must make it less, not more. Yes I solved both the ...
In the open position, the torque of the claw is small, below \(0.2\,{{{\rm{Nm}}}\). This results in a required force to release of 11.4 N at the tip of the contact zone, well below the forces encountered on impact, even at low speeds. Claw locking The torque that the claw...
What device is used to measure internal combustion engine torque? An inhomogeneous magnet of deflection radius 0.6 m is used to provide simultaneous imaging in both planes, from the beginning to the end of the magnet. Determine the inhomogeneity index and the deflection angle for which this occurs...
For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity. The "delta" Δ in front of the t means it's a change in time that can be written as...
I also approached it another way in the meantime using torque and momentum as change in momentum is equal to net torque and got the acceleration as negative. The only way I was able to get the correct answer for the question was when I ignored the negative sign on acceleration. I will ...
How do we describe motion - College of Charleston
angular momentum to create stabilizing torque, which directly opposes the wave-induced rolling motion. Note that the precession oscillation is caused by the rolling motion, in a plane at 90 degrees to the rolling motion (the pitch axis), and then, in turn, the stabilizing torque is caused by...
Moment of inertia in the atmosphere is determined by mass distribution, and angular velocity is how fast the air mass is rotating. Unless an external torque acts on an isolated system, the total angular momentum stays constant. Rotating air masses, like hurricanes or other types of cyclones, ...
The deduction of the momentum equation with reference to deflection starts from Hooke's law which is ϵ=σE Parallel to this concept we would have that with the flexion formula the equation would be, σ=−MyI If the two equations are united we would finally have ...
Angular acceleration is similar to linear acceleration, except that it travels along an arc. An example of angular acceleration would be an airplane propeller spinning to reach a required number of revolutions per minute (rpm). You can calculate angular
