The bolts in your diagram would experience shear stress. First you could calculate the weight force of the display by using mass x gravity. Then since you have 4 bolts divide your weight force by 4 to get the force per bolt. Once you have that you need to pick the material of your bolts and...

I did the problem in the standard x-y co-ordinate system and got the right answer that the book had.After I finished I realized that I used the same time equation for both the flat and rotated co-ordinate system. Since that equation comes from the sum of the forces in y for whatever system you...

Ok I will try it that way. I thought it may have been easier to have x' aligned with the incline but that is where things probably went wrong. Thanks.

The initial velocity makes an angle of 60 degrees with the x axis. That is clear from the diagram from the book. In my attempt at the solution I drew the x',y' coordinate system rotated 20 degrees CCW from x,y. I did this so the launch height and the landing height would be the same. The 70...

Homework Statement Below is screen shot of the problem. My friends book was ripped so some of the problem was cut off. Using the diagram I need to find d. The answer is supposed to be 7.42x10^4m. Below the problem is my attempt at the solution. Can someone tell me where I went wrong. As you can...

Yes I think I would need IP08. I have tried searching but have not found much. Is there a small inline connector that could meet these requirements.

I have a compression fitting that I am using to bring power into a pressurized vessel. On the side exposed to the enviornment there are 2 14 AWG 24" long leads. This vessel is going to be under water. So I need a way of creating a waterproof connection to each of the 24" leads so I can have a...

I have a simple question. If when mixing two liquids together the directions say mix 10.4 parts of hardner by weight for every 100 parts of resin and I want the final mixture to be 2.75lb, could I do the following? Mh = mass of hardener Mr = mass of resin Mh + Mr = 2.75lb Mh/Mr =...

If you would like to work as an engineer than I think your best option is getting your bachelors in engineering. Going from a bachelors in Physics to masters in Engineering is going to likely be atleast a year of prereq engineering courses then the 2 years for the master degree plus your 2...

Anyone else care to weigh in?

I started an engineering program when I was 22. I am 26 now graduated and work fulltime as an engineer. IMO you will be fine. There was a pretty broad age range of students in my program starting with the standard 18 year olds to people in their 50's looking to start a new career. The most...

Yeah I use a CAD package to do the 3D models and 2D drawings and then those go out to the shop where a machinst will write a program and then machine the parts. I don't expect to start actually maching parts at my current job. I do wonder if knowing how to program in G code and use MasterCam...

I graduated 18 months ago with my BSME degree and currently work full time as a Mech. Engineer. I enrolled in night school at a local community college to take a CNC machining certificate course this spring. The course is 2 semesters long and focuses on opereation of CNC equiptment mostly lathes...

Each RJ45 accepts 2 wires. So would I need to find one that works with 4 or could I just use 2 RJ45 connections to connect my 4 wires inside my cable.

Can someone suggest a product or point me in the right direction of something that will do the following. I have a 24V DC LED panel connected to a dimmer by a cable that has 4 conductors with a 24 AWG size. I need to put a quick connect between the dimmer and the LED panel. The smaller this...
