Calculate the internal force in each bar for the roof truss as shown below. For each bar, indicate if the internal force is tensile or compressive. Use the node method (knutpunktmetoden). Point A has simple support and D has roller support.

5. A part of robotic link is shown below and links are designed with yoke. Two links are joined by a Hinge pin and each side is supporting a load of P = 14 kips. Consider that the shearing stress of the pin is 12 ksi and bearing stress is 20 ksi, find the diameter of the pin and the minimum thickness of the link's yoke.

Calculate the forces in members BE and BD of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F = 7.5 kN, a = 2.5m, b = 3 m, c = 2 m, and d = 2 m. A F Answers: BE= BD = a i i B b E a b O KN KN

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Consider the given structure with P= 952 lb. Во 12 ft The force in member AB is The force in mémber BC is P Using the method of joints, determine the force in each member of the truss shown. State whether each member is in tension (7) or compression (C). The force in member AC is 3.75 ft 9 ft lb (Click to select) ✓ lb (Click to select) V lb (Click to select) ✓

Problem 2: Determine the forces in all diagonal and horizontal members of the truss shown below using the method of sections. Determine the force in all vertical members using the method of joints. Hint, the structure is symmetric. The distributed load is transferred to the truss from the roof purlins. State whether the members are tension or compression. Summarize your results on a sketch of the truss. 2.5 k/ft H M K 12 ft A G B C D F 6 @ 12 ft = 72 ft

Consider the truss shown in (Figure 1). Set P₁ = 8 kN, P₂ = 10 kN, and P3 = 6 kN. Figure E ZA B C 3m P₁ P3 3m < 1 of 1 P₂ -3m- 3m D. ✓ Correct ▼ Part D Determine the force in member BF of the truss and state if this member is in tension or compression. Express your answer to three significant figures and include the appropriate units. Enter negative value in the case of compression and positive value in the case of tension.

A simple pin-connected truss is loaded and supported as shown. The truss is constructed from three aluminum members, each having a cross-sectional area of A=1480 mm². Assume a-1.5 m, b-6.5 m, and c-3.8 m. If P-55 kN and Q-90 kN, determine the normal stress in each member. L. Answers: JAB" OBC= MPa (C) MPa (T)
