There’s Something Missing ! Forces There’s Something Missing !
What happens here? F We get to find F ! ! 30º 75 N We get to find F ! ! Find the forces acting horizontally F = 75 cos30º F = 64.95 N
How about here? F F We get to find F ! ! 40º 30º 25º F 75 N We get to find F ! ! Find the forces acting horizontally 75 cos30º = F cos40º + F cos25º 64.95 = F(cos40º + cos25º) F = 64.95 ÷ (cos40º + cos25º) F = 38.1 N
These forces are in equilibrium, find the missing force These forces are in equilibrium, find the missing force! answers in Newtons to 1 d.p. F 9N 7N 15º 3N 30º F 50º F 12N 8N 6N 11N Check here 7N F 32N 15N 35º 38º 17º 10º 45º F 40º 60º F 21N 8N 58N 1N
