4. A round, horizontal, simply supported steel bar is subject to an axial compressive load, P = 5 kN, at each end acting at its centroid. Due to space constraints, the maximum deflection of the bar cannot exceed 350mm. Considering only the weight of the bar determine (a) the allowable span of the beam from points A to B, aka the total length of the beam in meters, and (b) the radius of gyration of the bar in millimeters. Let d = 60mm, E = 210 GPa, v = 0.30. The specific weight of the steel is 77 kN/m³. Note: the maximum deflection of a beam due to its own weight is vmax = 5pL4 384EI' where p is the distributed load in N/m.

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass
I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.
Please answer complete question

I need answers to questions 1, 2, and 3 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.
Please make the charts for the questions. Please refer to Successful Project Management (7th Edition). Attached is the example Thank you.
Don't answer if you already answered this. If i see the same solutions, i'll downvote you. Follow the instructions. Typewritten for upvote. No upvote for handwritten. Thank you
Answer the questions below, (Insert the numerical value only, do not use ,+, *, or /) The Relative error for your answer should be less than 0.01, which means if the answer was 50, then the error should not exceed 50*0.01= ±0.5! if the answer was 230, then the error should not exceed 230*0.01= +2 3! if the answer was 2.31467*10^ 3, then you should enter this value: 0.00231467, not this 0.0023 !!!!
