En un experimento llevado acabo en el laboratorio de física , se utilizo un posicionador cuántico para mover a cualquier posición cargas puntuales. Utilizando esa herramienta se posicionaron dos cargas en el espacio, la primera, de 40 nC en la posición (3.0 m, 4.0 m, 0.0 m) y la segunda de -35 nC en la posición (-2.0 m, 3.0 m, 0.0 m). Posteriormente se le requiere que se mida el campo eléctrico generado en un punto (0.0 m, 5.0 m, 0.0 m) y brinde la dirección mediante un vector unitario.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
