Answer 1

Given that F-1 = 200 lb F_2 = 100 lb Now, consider all the forces along x - direction and equate to zero Sigma F-x = 0 A_x + B_x + F_2 cos 45 sin 30 = 0 A_x + B_x + 100 cos 45 sin 30 = 0 A_x + B_x + 40.96 = 0 equation (1) Now, consider all the forces along y - direction and equate to zero sigma F_y = 0 A_y + C_y - F_1 cos 45 + F_2 cos 45 cos 30 = 0 A_y + C_y - 200 cos 45 + 100 cos 45 cos 30 = 0 A_y + C_y - 141.42 + 61.24 = 0 A_y + C_y -79.96 = 0 equation (2) \r\n Now consider all the forces along the z - direction & equate to zero Sigma F_z = 0 B_z + C_z - F_1 sin 45 - F_2 sin 45 = 0 B_z + C_z - 200 sin 45 - 100 sin 45 = 0 B_z
