Unformatted text preview: is used?45 kNm 2. The required section modulus Sx for a structural steel Wbeam is 16.1 in3. What is the least expensive Wbeam that can be chosen?W 12 x 16 3. For a 12 m long beam, a concentrated load of 5 kN down is applied at the midpoint. What happens to the shear plot at this point? What happens to the moment plot at this point?result (on back) 4. For a 12 m long beam loaded with only a single moment at the center, describe the shear curve. What happens to the moment curve at the point of application of the concentrated moment?result (on back) 5. Suppose a beam is loaded with a single distributed load (down) of 3 kN/m which is constant and extends from one end to the other. What is the value of the shear at the midpoint of the beam?zero...
