In a do‑nothing machine, two sliders are confined to perpendicular channels and are connected by a rod. the rod can be rotated, causing the sliders to move back and forth in their respective channels. suppose that the channels line up with the x‑ and y ‑directions and that the slider in the x ‑channel has velocity vx at some instant. let theta be the instantaneous angle of the connecting rod with respect to the x ‑direction. the length of the rod between the two sliders is l. find an expression for the instantaneous velocity vy of the slider in the y‑channel. express your answer in terms of vx, l, and theta.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.

Part of a control linkage for an airplane consists of a rigid member cb and a flexible cable ab. if a force is applied to the end b of the member and causes it to rotate by θ = 0.5°, determine the normal strain in the cable. originally the cable is unstretched.
