- A fixed centrode is locus of points of intersection of follower and extended crank.
- A moving electrode is the locus of intersection of follower and extended crank of the inverted mechanism.
- The use of moving and fixed coupler is to replicating the motion of a coupler (by moving the moving centrode over the fixed centrode).
- Explanation to be given in detail with the help of a neat diagram and the changing positions to be indicated clearly.

The rod of the fixed hydraulic cylinder is moving to the left
with a constant speed va=18 mm/s. Determine the acceleration aB of
slider B when sA=345 mm. The length of the cord is 1385 mm, and the
effects of the radius of the small pulley at A may be neglected.
The acceleration aB is positive if up.

The beat detected on a moving platform.
A speaker fixed to a moving platform moves toward a wall,
emitting a steady sound with a frequency of 230 Hz . A person on
the platform right next to the speaker detects the sound waves
reflected off the wall and those emitted by the speaker.
Part A.) How fast should the platform move, vp, for the
person to detect a beat frequency of 2.00 Hz? Take the speed of
sound to be...

21. For a particle of mass, m, moving along a circular path in the xy plane at a fixed distance, r, from the center and with no forces acting on it (V(x)-0), answer the following. Note the similarity to the hydrogen atom. We have an electron moving in the plane of a circle around a nucleus. Note the similarity between the Laplacian below and the azimuthal term in the hydrogen system Write the Schrödinger equation for this system. The Laplacian...

Write a function cycle(input_list) that performs an "in-place" cycling of the elements of a list, moving each element one position earlier in the list. Here "in place" means the operation should be performed by mutating the original list, and your function should not return anything. Note that you may assume that input_list is non-empty (i.e. contains at least one element) For example: >>> l = [1, 2, 4, 5, 'd'] >>> cycle(l) >>> l [2, 4, 5, 'd', 1] >>>...

A charged particle is outside of a fixed magnetic field. It is moving in a straight line, accelerating from rest through a potential difference V. When it enters the magnetic field, the particle's path is oriented perpendicular to the magnetic field. The magnetic field deflects the particle into a circular arc of radius R. If the accelerating potential is doubled to 2V, what will be the radius of the circular arc? Express your answer in terms of multiples of R....
