1. Wordoku solver in C

Homework Statement I'm fairly new to programming and I'm trying to write a program in C to solve wordoku (sudoku with letters) problems recursively, but I seem to be having some trouble with the recursion part of it. The user enters in a string of characters which will make up the 9 allowable...
2. Find the magnitude of a force supported by a bearing

Homework Statement Find the magnitude of the force supported by bearing B if the weight of the assemble is supported entirely by A and there is a 120 Nm couple to the shaft. The plate has mass of 15 kg. The cable from C to D prevents the plate from turning...
3. Find the tension in a cable and the reaction about a point

Homework Statement Find the tension in the cable CD and the reaction at point B. a=1.5 m w= 50 kg http://img821.imageshack.us/img821/5595/cusersjoshappdatalocalt.th.png [Broken] Uploaded with ImageShack.us Homework Equations Sum of forces=0 Sum of moments=0 The Attempt at a Solution I'm...
4. Determine Tension in a Cable

Homework Statement a) A rectangular plate is supported by three cables. Knowing that the tension in cable AB is 405N, determine the force at B. b) For the plate in the above question determine the force in cables AB and AD knowing that the tension in AC is 54N. The Attempt at a...
5. Adding Couples in 3D

I did. Good catch and thanks a lot
6. Adding Couples in 3D

Then I guess this question isn't that complicated at all. If you number the couples 1-3 going from left to right: M1x=0 M1y=1.5cos20 M1z=1.5sin20 M2x=0 M2y=1.5 M2z=0 M3x=0 M3y=1.75cos25 M3y=-1.75sin25 Therefore MRx=0 MRy=4.496 MRz=-0.2265 MR has a magnitude of 4.5012 And...
7. Adding Couples in 3D

Homework Statement Replace the three couples with a single resultant couple. Specify its magnitude and direction of its axis using angles to the positive x, y, and z axes. Homework Equations M = r x F (r cross F) The Attempt at a Solution I'm pretty sure I want to resolve the...
8. Determine the angle which will cause the greatest torque

We don't use it in the course, but it did cross my mind to take a look at the first derivative and go from there. I guess thats looking more and more like the way to go.
9. Determine the angle which will cause the greatest torque

I was able to get that far, but I'm just having trouble with finding that value for \theta. The way it is right now I can't see any way forward other than just factoring out the F...but that doesn't get me any closer.
10. Determine the angle which will cause the greatest torque

I'm not seeing what you're getting at. Maybe its just the wording of your response.
11. Determine the angle which will cause the greatest torque

Homework Statement Given F, b, and h, determine the angle θ which will cause the greatest strain. http://img844.imageshack.us/img844/5595/cusersjoshappdatalocalt.th.png [Broken] The Attempt at a Solution I know to break it up into components so that I get Ma = F(bcosθ+hsinθ). But after that...
12. Determine the moment about a given point

so I can use 1.8m as the vertical distance, but by the way it looks I guess I have to find out the length of x and add it to 7 in order to find the horizontal distance.
13. Determine the moment about a given point

Homework Statement I'm trying to find the moments about points A,B and D respectively. Homework Equations Mx= F * d The Attempt at a Solution Correct me if I'm wrong, but on point A the leftmost force produces no moment. After that I'm a little confused about what to use for the...
