3. Tres perros A, B y C encuentran un hueso ligado a tres cuerdas. Cada uno de ellos tira de una cuerda, si el perro A hace una fuerza de 10 kg. Y el hueso no se mueve. ¿Cuáles son las fuerzas de los otros 2 perros ?, si el perro B lo hace sobre el eje x negativo, C a 53 ° hacia abajo del eje x positivo y A lo hace a 37 ° hacia arriba del eje x positivo.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
