B) Specify its location of the force, measured from point O.

Part A Replace this loading by an equivalent resultant force. Suppose that w -2.5 kN/m and 2 7 kN/m (Eiaure 1) Determine the equivalent resultant force Express your answer to three significant figures and include the appropriate units. Enter positive value if the downward.

Explanation / Answer

W1 = 2.5 KN/m and W2 = 7 KN/m

F1 = W1 * 2 M

= 2.5 * 2

= 5 KN

F2 = 1/2 * W2 * 1.5

= 1/2 * 7 * 1.5

= 5.25 KN

(A) the equivalent resultant force

FR = F1 + F2

= 10.25 KN

(B) Specify its location of the force

FR * d = F1 (2/2) + F2 (2+1.5/3)

10.25 * d = 5 + 5.25 * 2.5

d = 1.768 m from point O
