When the two forces are in the same direction, the resultant force is a; when the two forces are in the opposite direction, the resultant force is B. when the two forces are perpendicular to each other, what is the resultant force?

When the two forces are in the same direction, the resultant force is a; when the two forces are in the opposite direction, the resultant force is B. when the two forces are perpendicular to each other, what is the resultant force?

Under the root sign (2 * a ^ 2 + B ^ 2), divide by 2

As shown in the figure, there is an object with a weight of 40n on the horizontal plane, which is still under the horizontal force of F1 = 13N and F2 = 6N
Let the maximum static friction be equal to the sliding friction, and find the magnitude and direction of the friction.

Answer: the maximum static friction FM = μ g = 8N (1) ∵ f-f2 = 7n ﹤ FM ∵ the static friction F1 = F1-F2 = 7n, horizontal right. (2) ∵ F2 = 6N ﹤ FM ∵ the static friction F2 = F2 = 6N, horizontal left (3) ∵ F1 = 13N ﹥ FM ∵ relative to water

The magnitude of the three forces are F1 = 4N, F2 = 5N and F3 = 6N. Given that the resultant force is 0, what is the magnitude and direction of the resultant force of F1 and F2?

The resultant force of F 1 and F 2 is 6N and the direction is opposite to f 3
Memory a rule: 3 force balance, any 2 force resultant force and the third force, etc
