1) A lead screw and saddle arrangement is used to lift a load of 200 kg. The square thread has a pitch of 8 mm and a diameter of 30 mm. The coefficient of friction is 0.2. Calculate the torque needed to rotate the screw on raising and lowering.
2) A screw Jack must raise a load of 500 kg. The thread has a pitch of 10 mm and a diameter of 50 mm. The coefficient of friction is 0.15. The effort is applied through a lever of radius 400 mm. Calculate the efficiency and the effort required to raise the load.
3) Find the greatest and smallest values of the velocity ratio of two shafts joined with a universal coupling when the axis are at 38.
4) Explain what conditions are required in order to obtain a constant velocity joint for the universal coupling mentioned in part a). A suggested word count of 150 words 10% is required for this task.
5) Select and examine two different types of mechanica
Overview
Imagine you are the manager of a software development team working on new applications for your company, Optimum Way Development, Inc. The Marketing department has asked you to create a blog post that they can post on the company website to promote one of the applications your team is developing. The audience for this blog post is non-technical potential customers. You asked one of your developers to draft the blog post, which you will then revise before sending it to the Marketing department. The developer has just sent you the draft of the blog post.
Prompt
Review the attached blog post and revise it so the blog post uses appropriate:
Style and tone
Inclusive language
Technical language/explanation
Writing mechanics (e.g., spelling, grammar, punctuation)
You will be modifying the actual blog post to create a final product that can be given to the Marketing department (i.e., you will be making the desired changes within the document, not providing edit
You have a syringe which is filled with 10 ml of water.
The inner diameter of the main body of the syringe is 15.9 mm, and the inner
the diameter of the outlet is 1.2 mm. With how much force you have to press
the plunger for clearing the syringe for water within 10
Seconds? You can overlook the friction of the piston and the viscosity of the water.
Now place a needle on the syringe, with a length of 25 mm and inner diameter
0.210 mm. If you press the plunger with the force 0.10 N, how long
will it take to empty the syringe? Now you can no longer ignore the viscosity
to the water, which is = 0.0010 Pas.

Tasks:
1. Download the file cache.c from the Assignment8 drop box.
2. Implement code at each comment containing TODO: that performs the operation described in the comment.
3. The code includes unit test code that calls the various cache management and virtual memory functions. Verify your code works but using that unit test.
Need this assignment written up in C#, the top 10 displayed movies algorithm can be done using a bubble sort algorithm
A demonstration can be seen here: https://echo360.org.au/lesson/cc8d6b2c-197e-43c3-97fd-54aae4e48620/classroom#sortDirection=desc
and also here: https://echo360.org.au/lesson/fe8df1dc-bc25-4edd-a012-4c145a39b56c/classroom#sortDirection=desc
I have attached the project specification as well, if it can be done ASAP that would be awesome. Also the binary tree code is in the Zip file as well
Thanks
Scientists have developed a type of panel that can generate electricity from rain,
by keeping some of the motion energy in the raindrops that hit the panel
converted to electrical energy.
a) I tested the research loop and easily killed 100 microliters from one
height of 15 cm above the panel, and measured that it can generate an electrical energy
at 3.24 uJ. What percentage of the motion energy of the kill is converted
for electrical energy? Disregard the air resistance
B) Suppose a typical rain shower consists of almost spherical raindrops
with a radius of 1.7 mm. (These have less volume than those in the previous sub-question.)
For drops that fall from high altitude we can no longer ignore
air resistance. It is given by the formula
------1/2*lv*2CDr2
there l = 1.23 kg / m3
is the density of the air, v is the speed of the kill, r is the radius
to the kill and CD = 0.7 is a constant. What is the greatest speed and death will
get, termina
This assessment is related to a group project that have been submitted by four students. I have attached the project under the name of "final report assessment 2." My part on this project was from 2.1 to 2.2.1 which is:
2.1 - Design a photovoltaic solar system to provide a specific energy.
2.2 - SolidWorks design.
--------------------------------------------------------------------------------------------------------
Things you need to consider on the contribution:
- Due to COVID-19 we did not have the opportunity to have more than three meetings.
- We had meeting on the following dates:
@ 4th of march. We met with prof where we discussed how we will continue working on the project with keeping social destine and we will not be able to meet on the university canvas and build the prototype. So we will make a research and prepare a report for other students to build the prototype in the future.
@19th of march. We meet the prof to re-scoped the project
Good Evening to whomstever is helping me with this aching assignment(:
I honestly tried doing this lab but I gave up, I never understood this lesson in chemistry class. Anywho this is from my lab. Values were given to us, and Im not sure you can tell. But in pencil, I was only able to solve the differences lol. There is a video that goes alon with this but it was really no help when I watched, but ill add it here just in case if needed, https://studentlaccd-my.sharepoint.com/:f:/g/personal/milligja_laccd_edu/ErRKqv-vrpVLlS44UtvMbxMBAM1nrP64LcN5HGOA2IzhwA?e=BZvGvD
But yes, the directions are right forward, I just cant solve anything with my 3 brain cells.
I honestly just need help creating the code or some guidance to help make a tictactoe game. I have the design I just don't know which functions to create. Here is what I have so far: https://studio.code.org/projects/applab/ry5Ou1hK7zZOTd113LIf5xfIJpcWrydmc3VZqb4ZaxU
