Question 1)
The simply supported beam AB is constructed of A572 Grade 50 steel
and is subjected to 3 seperate concentrated loads at which the beam
is laterally braced as shown. It is required to find the lightest
W-section for the beam to dafely support the loads.

Question 2)

a) determine the number of bolts required

b) Pb= 200 kips what is the maximum tensile live load?

Student N This isa Notes: I that s 2. Marks are assi 3. The exam contains four obligatory questions ABshown in Figure 1 below is constructed of A572 Grade 50 steel and The simply supported beam is subjected to three separate concentrated loads at which the beam is laterally braced as shown. It is required to find the lightes W-section for the beam to safely support the loads shown. 20 k 20 kips 20 kips 6 fr 6 ft uestion (2) (20 Figure 2 below shows a front view of a lap connection between a group of 1 steel A36 steel. The connection transfer a load of P-520 kips and it is a bearing-type connection with A325X bolts of 0.75-diameter each. The bolts are to be placed in two transverse lines (each has same number of belts) as shown in the figure below. Assuming that the plates are safe: a) Determine the number of bolts required to have a safe bearing-type connection b) If the tensile dead load acting on your designed connection is PD 200 kips, what is the maximum tensile live load P that can be carried by the connection.
