(1) In circular pipe flow of diameter (D), the maximum discharge is most likely to occur at the following depth: (1) D (2) 0.5 D (3) 2D (4) 0.95 D (5) 0.75 D (ii) Given the area (4) of a rectangular cross sectional flow = 3 m², and the wetted perimeter (P) is 5 m then the hydraulic radius (Ra) is. and conveyance (K) of the cross section is (1) 0.6 , 2.134 (2) 1.667, 15 (3) 1.2, 1.068 (4) 0.6, 1.5 (5) 1.667, 2.134 (ii) If the flow in a pipe is laminar and the Reynolds number is 1000, then the friction factor is approximately (1) 0.064 (2) 0.128 (3) 0 (4) 1 (5) Infinity (6) 1000

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

where does the 64 come from?

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…
