Hi there, again maybe stupid question but I have no idea about this exercise. or maybe a little clue. i know that v=r? but with the given 40° when i convert it to a rmp it is very small value 0.111111 and the r is 3m or 7m.. Please if someone can help me.. also if someone can help me with the FBD of A wheel being hauled up a slope by a wire attached to its axle.
