The link arrangement shown is frequently used in highway, Ask an Expert

Engineering

The link arrangement shown is frequently used in highway bridge construction to allow for expansion due to changes in temperature. At each of the 60-mm-diameter pins A and B the coefficient of static friction is 0.20. Knowing that the vertical component of the force exerted by BC on the link is 200 kN, determine

(a) the horizontal force that should be exerted on beam BC to just move the link,

(b) the angle that the resulting force exerted by beam BC on the link will form with the vertical.
