There are two samples, A and B, ere tested by Rockwell hardness test. Sample A is tested in B scale, shows hardness value 59 HRB. Sample B is tested in F scale, shows hardness value 90.5 HRF. Which sample is harder? I. Sample B II. No way to compare sample A and B. O I. Sample A and B are same. OV. Sample A

Solve both and show all parts and solutions

03. Circle the letter corresponding to the view on the right that shows the result of rotating the object on the left by the indicated amount.

I need help matching the following terms to the phrase it describes. Answers are used only once.

The beam in the figure below is subjected to a load P= 3.9 kN at its end. Young's modulus is 210 GPa and the moment of inertia for the beam's cross-section is 5×106 mm4. P If a = 1.5 m and b= 1.3 m, determine: A F a B |-x₂ b Tuc

The answer is one of the options below please solve carefully and circle the correct option Please write clear .

Finish the Orthographic drawing

Draw the 1st and 3rd Angle Orthographic sketch of the following part:

can you write step clearly

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…
