IGCSE PHYSICS - PRESSURE (7)

because oil. being less dense, makes the manometer more sensitive: for the same pressure difference, the oil will move further. The pressure difference between the two regions is given by the following equation: Ap = hdg This is basically the same equation as p = h x d x g.

Example: Pendulum equation with friction x˙1 = x2 x˙2 = − asinx1 − bx2 V (x) = a(1− cosx1)+ 1 2 x2 2 V˙ (x) = ax˙1 sinx1 +x2x˙2 = − bx2 2 The origin is stable V˙ (x) is not negative definite because V˙ (x) = 0 for x2 = 0 irrespective of the value of x1 – p. 13/15

Now I will include friction in my problem: x¨ +sx˙ +sinx = 0, s > 0. I can rewrite my equation as the system x˙ = y, y˙ = −sy +sinx, which has the same equilibria as the conservative pendulum equation. Here, however, I can use the standard linearization approach to conclude that the origin is locally asymptotically stable (do this).

friction between the disks is Pk = 0.15. Bearing friction can be neglected. Determine: a) the angular acceleration of each disk, b) the final angular velocity of each disk. Problem 4.8 A gear reduction system consists of three gears A, B, and C. Gear A starts from rest at time t = 0 and rotates clockwise with constant angular acceleration.

friction so that the spring oscillates with SHM how much energy is kinetic and potential when the spring is at (a) x = .10 m, (b) x = .0 m Let’s suppose that the spring is not horizontal, but is instead in a vertical position. The motion is basically the same as a horizontal spring except for where the equilibrium position is located.
