The pin-connected structure shown in the figure consists of two cold-rolled steel (E = 30,000 ksi) bars (1) and a bronze (E = 15,000 ksi) bar (2) that are connected at pin D. All three bars have cross-sectional areas of 0.375 in². A load of P = 11 kips is applied to the structure at pin D. Using a = 3 ft and b = 5 ft, calculate the downward displacement of pin D.

You are given a metal rod, cut to a length of 12 in plus/minus .25in. Then you need to cut off 2 in with an accuracy of plus/minus .25 tolerance. You end up with a 10 in rod but what is the tolerance? (hint: rely on the basic principle of tolerance

Each cylinder of six cylinder internal combustion engine has a diameter of 60 mm and a stroke length of 400 mm. What is the engine capacity in litres? Give your answer to 2 decimal places.

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…
