Statics of Rigid Bodies pros. I badly need your help, please?

1. If a 200 kN load is hanging from a ceiling by means of rope, which makes a 70 degrees angle with the ceiling, determine the horizontal force H responsible for the inclination, and the tension T in the rope.2. The unstretched length of an elastic cord is made to run vertically from the ceiling down to the floor. If the mid-portion of the elastic cord is pulled with a 15 kN horizontal force, thus stretching the cord and making the cord incline with a slope of 4/5, determine the tension in the cord.3. A concurrent force system consist of three forces with magnitude of 120,50 and 130 kN. What are the angles among them assuming that the force system is in equilibrium?4. A 20 kg ball snuggly fits inside a cube, whose bottom is tipped at 45 degrees from the horizontal. Determine the reaction of the bottom of the cube due to the weight of the ball. Assume forces are smooth.Having a hard time and I need an idea. I'm not sure of what I have.. Share your knowledge please.. Thank you!

The vertical forces are in balance, so200 kN = T cos(70) andT = 200 kN/cos(70) = 585 NH = T sin(70) = 549.5 NCord problem:15 kN = T (3/5) => T = 25 kNThree concurrent forces:Without loss of generality, position the 130 kN force F1 along the positive x-axis.The 120-kN force F2 must then point somewhere in the 2nd or 3rd quadrant;it doesn't matter which we assume, the difference will just be a mirror image.So assume F2 points into the 2nd quadrant.The 50-kN force F3 must now point into the 3rd quadrant.Let A2 be the angle between F1 and F2; let A3 be between F1 and F3.50 cos(A3) + 120 cos(A2) + 130 = 0..........."equation (1)"50 sin(A3) = 120 sin(A2)A3 = arcsin[2.4 sin(A2))Therefore, cos(A3) = sqrt[1 - 5.76 sin^2(A2)]Plug this in to "equation (1)" and you have an equation whoseonly unknown is A2. Also note that cos(A2) = sqrt[1 - sin^2(A2)].Then the only unknown in "equation (1)" will be sin(A2),and the equation can be solved by algebra alone (and a trig table).Ball: I guess they mean the cube now rests on one edge.The weight of the ball is then exactly "split" between the two cube facesupon which it rests. Answer: (1/2)mg = 98 N.

How can i lose weight super fast? No matter what.?

I need to lose weight really fast. Like thirty pounds at least. In the next two weeks. I don't give one crap about whether it's healthy or not. I need to lose this now.

How to Lose Weight by Walking Fast

Recommended Answer:

Run! Do cardio and light weight lifting. Dieting is 80% of losing weight so be sure to eat 5-6 times a day, keeping your calorie intake to abotu 300 calories per small meal. It doesn't seem hard but once you see how many calories you normally eat and compare it to the new lifestyle, you will be in shock. Keep count of how many calories you intake on everydayhealth.com. They have an excellent calorie calculator that I use myself. Don't go past your daily limits. I shed off a few pounds in a week without even working out by eating small, frequent meals. So I believe that if you work out and eat those frequent, low-calorie meals, then you will lose weight really fast! My friend lost 40 lbs in 3 weeks by doing so.

Other Answers:

• Hard work, patience, and good decisions.
• Not gonna happen, Tristin. Like another user said PATIENCE, hard work and so forth. Losing that much weight in the next two weeks is so unrealistic.

Hi, im currently obese (5''7 267 pounds) and I want to lose 60 pounds in 3-4 months. Is that possible? I plan to eat 1500-1700 calories per day & exercise for 1 hour and 30 minutes. I just want to know if it''s possible. I don''t care if it''s unhealthy, I plan to eat healthier once I get to my goal weight. So please only answers that answer my question please.

How to Lose Weight?

Recommended Answer:
Yes, I believe it is possible. I didn''t exercise as much as you plan too and I was able to lose 30 pounds in 12 weeks. I have kept it off for 2 years now. I did a little research and came up with my own plan.

If you want to see what I did to lose weight I wrote about it at http://www.squidoo.com/how-to-lose-weight-without-starving-yourself2
It doesn''t cost you anything, I didn''t take any diet pills or join a weight loss company, I just wanted to share my story. Check it out and see if you think what I did could work for you.

• It actually is very possible but you would have to do intense workout. You can still get all the nutrition you need by eating little. Just make sure you get all the required daily needs to keep you healthy. Get someone to motivate you also because that helps a lot. They keep you on game.
