The 25-kg block shown in figure moves on a plane with two attached springs. Determine the
acceleration of the block at B using Force and acceleration. The spring1 has a stiffness k1 =
200 N/m and unstretched length is 0.4 m. The spring2 has a stiffness k2 = 100 N/m and
unstretched length is 0.7 m. The coefficient of kinetic friction between the crate and the plane
is μk = 0.3.
The rod OA in Figure rotates in the horizontal plane such that θ = sin(t) rad. At the same time,
the collar B is sliding outward along OA so that r = 10t mm. If in both cases t is in seconds,
determine the velocity and acceleration of the collar when t = 1 s.
Find the power absorbed by each components, label P1, P2, P3 and P4.
plot a graph of distance (s) vs time (t) for the first 10s of motion if u= 10ms-1 and a= 5ms-1
You have to design a logical circuit for a 4-bit composite number using K-MAP (SOP minimization). Provide the original and simplified Boolean expressions in SOP form. Covert SOP to POS using the K-Map.
An iron ring uniformly wound with 1200 turns of insulated wire and a magnetizing current of 1.25 A produces a flux of 1 mWb in the air gap. The mean circumference of the ring is 50 cm and cross-sectional area of 20 cm². A radial air gap of 0.5 mm is cut in the ring. Neglecting the effect of magnetic leakage and fringing, caluculate (a) the reluctance of the magnetic circuit and (b) the relative permeability of iron
