Strength Of Materials Answer should be 45 kN/m; 0.26 cm :) A compound girder consists of a 45 cm by 18 cm steel joist, of weight 1000 N/m, with a steel plate 25 cm by 3 cm welded to each flange. If the ends are simply-supported and the effective span is 10 m, what is the maximum uniformly distributed load which can be supported by the girder? What weld thicknesses are required to support this load? Allowable longitudinal stress in plates = 110 MN/m2 Allowable shearing stress in welds = 60 MN/m2 Allowable shearing stress in web of girder = 75 MN/m2

From the given truss shown, computethe forces in members BC, CD, and CG. Given the allowable shear stress of 70 MPa and the allowable bearing stress of 140 MPa. Compute how many 10 mm-diameter rivets are required to fasten member CG to the gusset plate. Give me the solutions of this please. The answers are: BC=1.155kN(T),CD=5.20kN(T), CG=4.04 kN(C), n = 3 rivets
A howe truss has six panels and each panel is 1m. The span is 6m and height 1.50m. Joints U1, U2, U3, U4, and U5 each carry a vertical full panel load PL = 2600lb and joints L0 and L6 each carry a vertical half panel load PL/2 = 1300lb. Find the value of the stress of member L2L3.

PROBLEM: Light grade steel channel was used as purlin of the truss. The top chord of the truss is inclined 1V:3H and the distance between the trusses is 5m. The purlin weighs 100n/m and spaced at 1m apart. The roof carries superimposed dead load of 1000 Pa (including its weight) and the ceiling carries a load of 1200 Pa. Roof live load is assumed to be 1500 Pa. The roof is part of the building located at a place where the design wind speed is 240 kph. Assume the unit weight of air to be 12 N/m3. The windward coefficient is 0.20 and the leeward coefficient is 0.70. For this problem, assume that the allowable bending stress of beam is 60% and 75% of its yield strength in the strong and weak axis respectively. Assume all loads passes through the centroid of the section. Properties of C 250x85 ; Sx= 122 x103 mm3 ; Sy= 49 x103 mm3; Fy=300 MPa; Fbx (Allow. Bending Stress)=0.6Fy;Fby (Allow. Bending Stress)=0.75Fy What is the ratio of the actual to allowable bending stress for load…

2.) The Pratt roof trusses are uniformly spaced every 3.60 m. The deck, roofing material, and the purlins have an average weight of 0.15 kN/m^2. The building is located in the hills where the anticipated wind load is 2.10 kN/m^2. The wind load is assumed act perpendicular towards the top chord of the roof (side AHG only). Considering the given loads, determine the following: a.) Equivalent concentrated load on Joint A, H, G, F and E due to dead load b.) Equivalent concentrated load on Joint A, H and G due to wind load c.) Force in each member due to dead load and wind load. Neglect the weight of the truss members and assume A is pinned and E is a roller
