3. Consider two 2"x4" boards that are 122" long and glued together to form one 122" long beam. In case 1 they are glued together lengthwise along the wide sides while in case 2 they are glued along the narrow sides. If the ends are placed on 2 sawhorses 10' apart determine the maximum downward force in the center each could support. The glued surface in each case is parallel to the ground. Use 200 psi for the allowable glue shear stress and also use the actual dimensions of 2"x4" lumber. Also find the maximum bending stress for each case.

Solve the truss structure using the joint's method.
1. This arm is attached to a wall on the left. The right end is free hanging. Each section is 1.9m wide and 3.6m high. If the force at the end of the arm is F = 170.0N, what is the force in member 2? Use a positive number if it is in tension and a negative number if it is in compression. 2. This arm is attached to a wall on the left. The right end is free hanging. Each section is 1.2m wide and 3.0m high. If the force at the end of the arm is F = 150.0N, what is the force in member 9? Use a positive number if it is in tension and a negative number if it is in compression.
Q2: Determine the force supported by each member shown in Figure 2 by using method of joint. 5m 7.5m
Complete and do not shortcut the solution, show always the original figure, the free body diagram, the formulas, and the directions of force, and use the proper symbols.
width of the flanges, bf1 = 300 mm and bf2 = 215mm;depth, d = 375 mm;thickness of flange, tf = 45 mm;thickness of the web, tw = 57 mm(Note: Neutral Axis is the axis that passess through thecentroid. Give your answer in mm)
Solve the internal forces on the given beams. Problem Instructions: The cutting plane should pass through the midspan of the beam. From the midspan of the beam, consider 3 sections to the left, and 3 sections to the right. Each section should have its own free body diagram. Show that the internal forces at the left section is equal with the right section. NOTE: For consistency and accuracy, intermediate values must not be rounded off. Final answers must be expressed in four decimal places (final answers only). Final answers should not be expressed in terms of fraction or pi. Indicate proper units as specified in the problem.
angle between the string IS 52 degrees each String If the in find the tension 14.2kg
Note: End of the question answer also given if you got answer other than that values please leave it. Two long poles each 5.0 m tall, one of steel and one of hardwood (such as oak), are anchored vertically in a concrete slab so that only that part above the concrete can bend or be compressed. If the top of each is connect to the ground by a wire under tension to a point 1.0 m from its base, by how much does each bend and is compressed by this wire if it has a tension of 10,000 N. Assume that each pole has a radius of 6.0 cm. Answers: Δxwood = 87 μm, ΔLwood = 290 μm
