calculate the forces RA and distance d

Answer:
Explanation:
Sum vertical forces to zero (UP assumed positive)
Rₐ + 1.3 - 0.2 - 2.7 - 0.4 = 0
Rₐ = 2.0 kN
Sum moments about the2.7 kN force to zero (CCW moment assumed positive)
0.2(22) - Rₐ(10) + 1.3(d) - 0.4(d + 15) = 0
0.2(22) - 2.0(10) + 1.3d - 0.4d - 0.4(15) = 0
0.9d = 21.6
d = 24 mm
