Answer:
Weight needed to balance the bar is
Explanation:
Given the weight of the bar is
The length of the bar is
The weight of the bar will be uniformly distributed over the entire span. We will consider this as a point load acting in the middle of span length, which is at a distance of from both ends.
Now applying momentum equation about balanced load we get, (see attachment)
Answer:The horizontal forces can be summed as vectors in order to determine the net force. Fnet = ∑Fx = 5.20 N, right - 3.29 N, left = 1.91 N, right.
