Consider the crane lifting the load shownIf the maximum crane loading on member A is 40,000 lbs (18,140 kg) as a bending limit, calculate the heaviest load that can be liftedThe answer is Load 40,000/(cos 45-cos 80) 40,000/0.533 75.0 klbs but don't understund the equation !
The relaxer probably at least has a little to do with it.
of course relaxer is the reasonlots of chemicals r used to relax ur hair.it damagesn d effect can b worse if she did it from d rootsusing a flat iron is okbut use a thermo protection serum be4 staightenin.
flat ironhappening to my hair too nowIve been using the straightner for about 5 years and my hair used to be very healthy but recently ive got alot of split ends which have caused my hair to break easierThat is obviously happening to youI would recommend to use straightning balm; its a product that automatically striaghtens your hair without the use of a striaghtner its great but depending on howcurly your hair isAlso i wouldnt wash your hair every single day and flat iron it every single daySkip a few days on washing your hairConsider a bun or ponytail once in a while? ahope this helps~
Well tell you what your hair dresser knows that you should switch up on the relaxer once and a while and try anotherMe myself I do my own relaxer and cellophane (semi-permanant color) before I go to the shop and just pay for cut and style, because in my mind today stylist don't get you want you want when it comes to putting chemicals in your hairI also prefer a man to do my hair, because they know how to make the woman look dam good and women stylist don't have time, but only to cut more off than you ask for and everything you don't wantThe men stylist have growing hands to me and take good care of your hair.
OK,First of all we assume no friction in the pulley at the end of the jibSo the tension (T) in the cable is the same on both sides of the pulley and is equal to the maximum loadWhat we are looking for is the bending load on (A)In other words the force acting at right angles to (A) There are two forces here acting here i) The component of (T) down and to the right due to the cable between the pulley and the load T s(45) ii) The component of (T) up and to the left due to the cable between the pulley and the winch T s(80) So the net bending force is the difference between the two T s(45) - T s(80) T(cos(45) - cos(80) ) {Saves a bit of looking up if you know that cos(80) sin(10) } T( 0.707 - 0.174 ) T 0.533 But you are told that the maximum bending force 40000 lbs 40000 0.533T T 40000 /0.533 T 75047 lbs ≈ 75 klbs As we said earlier T load EDIT: If you are ever unsure whether it is sin() or cos(), ask yourself what happens if you do a thought experiment where you change the angle to 90° or 0° Here if the angle was 90° instead of 80°, the cable would be pulling with a tension (T) along the bar (A) so the component of (T) at right angles to the bar would be zero At 90°, sin(90°) 1 and cos(90°) 0 So T.sin(90°) T and and T s(90°) 0 So if you know that the answer IS zero, it must be cos() In the same way, if the angle was 0° the whole of (T) would be pulling at right angles to (A) At 0°, sin(0°) 0 and cos(0°) 1 So again, to get the right answer, (T), it must be cos()
