1A 170 lb man in the bosun's chair exerts a pull of 65 Ib on the rope for an interval of 2.75 seconds. Determine how far he went up if he started from rest. Neglect the mass of the chair, ropes, and pulleys.

You are in an inventory management field these days. You are working for a place which works on 365 working days per year. The annual demand is 901 widgets per year. The ordering cost is $111 per order, regardless of size. The holding cost is $6 per widget per year. How many orders per year will you place? Please round your answer to the nearest integer.

Round off the numbers in the following problems to three significant figures. Find the percent difference between each rounded-off number and the original number by using the original number as the reference.                  6748.3

8. Solve for Sin, Cos, and Tan for angle A with the diagram below for angle A. (Use Machinery's Handbook for Equations) Page # A.) SIN B.) COS C.) TAN a A b

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…

I need these three parts answered (Multiple Choice). If you can not answer all three parts please leave it for another tutor to answer. Thank you.   For the two holes identified as datum D, what is the total size tolerance specified for those holes? (Multiple Choice)a. .002'b. .003'c. .004'd. .006' The two holes identified as datum D have a counterbore on one end. What size toleranceis specified for the counterbore diameter? (Multiple Choice)a. .010″ (±.005″; see title block)b. .020″ (±.010″; see title block)c. .030″ (±.015″; see title block) What letter represents the revision status of this print? (Multiple Choice)ABCD

i) The displacement at point A. Enter your answer in mm to 2 decimal places.

Please do the last three questions (2, 3 and 4)! Thank you in advance!  A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center.  1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs?  2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction?  3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?)  4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did…

you solved it with a total distance of 8, not 10 like the question said. please resolve with a distance of 10
