1. In an engine rotating at 1500 rpm, a cam is used to open and close a valve during half of its rotation. The displacement of the valve rod is 25 mm. If the outstroke and return stroke is simple harmonic motion, (a) determine the maximum acceleration and velocity of the cam (b) also determine the displacement of the follower during cam positions at 30°, 60°, 90°, 120°, and 152° (Take 0° when the follower starts to move upwards). (c) During what position(s) of the cam does maximum velocity occur?

It is required to design a chain drive with a duplex chain to connect a 29 kW, 1400 rpm electric motor to a transmission shaft running at 350 rpm. The operation involves moderate shocks. During preliminary stages, the centre distance can be assumed to be 40 times the pitch of the chain. (i) Specify the number of teeth on the driving and driven sprockets. (ii) Select a proper roller chain. (iii) Calculate the pitch circle diameters of the driving and driven sprockets. (iv) Determine the number of chain links.
I asked for problems 6 and 7 to be answered, but I did not get a properly structured answered as the example shows on problem number 1. Here is the link to the questions I already had answered, could you please rewrite the answer so its properly answered as the example shows (Problem 1)? https://www.bartleby.com/questions-and-answers/it-vivch-print-reading-for-industry-228-class-date-name-review-activity-112-for-each-local-note-or-c/cadc3f7b-2c2f-4471-842b-5a84bf505857
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
That is the answer I already have, I am lookinf for the answers to the blanks in the image
Please do this carefully.
I am confused because on my homework i got marked wrong for this, unless I used to many sig figs.
It's saying this is not correct. Thank you for your help.
Answer this please. Thank you very much
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
Please walk me to find the answer and please include the magnitude of the force.
Do not give answer in image and hand writing
can you provide an answer easie to read. the answer is put into sentences like fcv=mgcos 6
