Solve a part only in 2 hours and get a thumb up this is mecahnical emgeering question so plz don't reject it QUESTION 1Use Figure 1, a pin jointed steel truss with bolted connections and the values presented in Tables 1 and 2, as well asyour mathematical thinking and reasoning to respond to the following questions.a) Ignoring the self-weight of the members, determine the support reactions.b) Ignoring the self-weight of the members, determine the force in the four members AB, AD, CD and AC.c) Design members AB, AD, CD and AC. Use Equal Angle (EA) Sections for members in Tension and assumethe member is bolted with 1 Hole in Leg. Use Square Hollow Sections (SHS) for members in Compression.For zero-force members use SHS 65x65x1.6.d) Determine the stress, strain and elongation/shortening of member AB (Assume Esteel = 200,000 MPa)e) Design the bolts for the connections on members AB, AD, CD and AC. Use the same "Grade:8.8" bolt sizefor all connections. That is, whatever bolt size is selected on one member, needs to be used on the otherthree members.f) The steel price is $16 per kg, and the bolt price is provided in Table 2. Determine the total cost of thematerial to build members AB, AD, CD and AC.Remember to include free body diagrams at part (a) and part (b) and your answers must be consistent with theorientation of the truss presented in Figure 1.

QUESTION 1
Use Figure 1, a pin jointed steel truss with bolted connections and the values presented in Tables 1 and 2, as well as
your mathematical thinking and reasoning to respond to the following questions.
a) Ignoring the self-weight of the members, determine the support reactions.
b) Ignoring the self-weight of the members, determine the force in the four members AB, AD, CD and AC.
c) Design members AB, AD, CD and AC. Use Equal Angle (EA) Sections for members in Tension and assume
the member is bolted with 1 Hole in Leg. Use Square Hollow Sections (SHS) for members in Compression.
For zero-force members use SHS 65x65x1.6.
d) Determine the stress, strain and elongation/shortening of member AB (Assume Esteel = 200,000 MPa)
e) Design the bolts for the connections on members AB, AD, CD and AC. Use the same "Grade:8.8" bolt size
for all connections. That is, whatever bolt size is selected on one member, needs to be used on the other
three members.
f) The steel price is $16 per kg, and the bolt price is provided in Table 2. Determine the total cost of the
material to build members AB, AD, CD and AC.
Remember to include free body diagrams at part (a) and part (b) and your answers must be consistent with the
orientation of the truss presented in Figure 1.
