Find the force FT,2 in the cord that is required to hold theframe in this position. Answer in units of N. (c.) Find the magnitude of the horizontal force at P that isrequired to hold the frame in this position. Answer in units ofN.Explanation / Answer
resolve into x and y components. Fx = F1cos50 - F = 0 Fy = F1sin50 + F2 - 14.7 N = 0 For the arrangement to be static. Now, balancing the torque about left-bottom corner, F2*0 + F*0 - F1*cos50*0.18 + F1*sin50*0.36 - 14.7*0.18 Nm =0 So, F = F1cos50 F2 = 14.7 - F1sin50 2F1sin50 - F1cos50 = 14.7 (a) => F1 = 14.7/(2sin50 - cos50) = 16.53 N (b) F2 = 14.7 - F1sin50 = 2.037 N (c) F = F1cos50 = 10.625 N
