  16. Term of energy, vector, resultante dan energy moment • Term of Energy If we are going to know what is energy, see and observe these experiences below. A ball is kicked so it will rotate, or there is a change of place of the ball. Technology and Reenginerring

  17. Term of energy, vector, resultante dan energy moment A rolling ball is kicked again, this will rotate a bit faster. It means there is a chage to the ball. Technology and Reenginerring

  18. Term of energy, vector, resultante dan energy moment A quite ball is placed in the corner of the wall. Having kicked, this ball doesn’t move at all. But, a fiew seconds there is change with ball. Technology and Reenginerring

  19. Term of energy, vector, resultante dan energy moment From the three experiences above that : “Energy is whatever things that may cause change of a place, movement or shape.” Technology and Reenginerring

  20. P = m x a Term of energy, vector, resultante dan energy moment P = energy m = weight a = speed Formula of Energy Technology and Reenginerring

  21. Term of energy, vector, resultante dan energy moment CHARACTERISTIC OF ENERGY HAVING A SIZE HAVING A LINE WORK HAVING A TARGET HAVING A SOURCE SPOT Technology and Reenginerring

  23. Term of energy, vector, resultante dan energy moment ENERGY HAS A SOURCE SPOT A target for the energy working The box is pushed on spot A, so the box will move to the right. Technology and Reenginerring

  24. Term of energy, vector, resultante dan energy moment The box is pushed on spot B, so it won’t move othetwise it plunges Technology and Reenginerring

  26. Pengertian gaya, vektor, resultante dan momen gaya HAVING WORK LINE Work line is a stright line scratching with that energy itself. Technology and Reenginerring

  27. Term of energy, vector, resultante dan energy moment Work line Work line An energy can be moved straight or Reverse as long as staying on its work line primary reverse straight Technology and Reenginerring

  28. Term of energy, vector, resultante dan energy moment Having a direction Energy has a direction to the left, right, upper side, under etc. Energy is a vector that is range that has direction. Technology and Reenginerring

  29. Term of energy, vector, resultante dan energy moment We can’t see energy but sense it. So, To describe energy in finishing building static problem, we need symbols. Symbol is scaling and direction line called Vector. Technology and Reenginerring

  30. Term of energy, vector, resultante dan energy moment For instance energy (P) = 100 kgs Energy scale 1 cm = 20 kgs so, vector length = Energy scale 1 cm = 20 kgs shows that 1 cm works for 20 kgs energy. Technology and Reenginerring

  31. VECTOR IMPORTANT TO FINISH BUILDING STATIC PROBLEMS BY USING PAINTING OR GRAPHICS Term of energy, vector, resultante dan energy moment Technology and Reenginerring

  32. Term of energy, vector, resultante dan energy moment RESULTANTE Organizing or adjoining energy or if two energies or more could be linked to be a resulting one called RESULTANTE. Technology and Reenginerring

  33. Term of energy, vector, resultante dan energy moment Resultante symbolized R See this picture: Having combined to R, It has a different height and direction. P1 = Energy 1 P2 = ENERGY 2 R = Resultante Technology and Reenginerring

  34. Term of energy, vector, resultante dan energy moment ENERGY MOMENT Moment is a situation in which action and reaction is not in the same work line. Energy moment is the Moment multiplied by Length. M = P x l M = Moment P = Energy L = Length Technology and Reenginerring

  35. Term of energy, vector, resultante dan energy moment Rules of moment : • If it rolls as straight as clock pointer, it’s called positive moment (+). • If it rolls inconventional, it’s called negative moment (-). SEE THIS PICTURES: Technology and Reenginerring

  36. Setting and dividing energy graphically and analitically Organizing Energy Arranging or adjoining energy is to determine resultante (R), it means two or more energies can be joined to be one called resultante (R). Technology and Reenginerring

  37. Arraning Energy analytically Graphically Image method Calculation method Setting and dividing energy graphically and analitically Achieved by two ways Technology and Reenginerring

  38. Setting and dividing energy graphically and analitically Arranging energy with image or graphically This method must involve energy scales and draw it properly. An error in imaging will effect the result. Technology and Reenginerring

  39.

  45. Setting and dividing energy graphically and analitically Grafically • Arranging energy with Paralelogram Arranging energy with paralelogram is so easy to do, but for one that is different direction and spot, may cause a complicated image. Technology and Reenginerring

  46. Setting and dividing energy graphically and analitically grafically Example: Decide energy resultante of P1 = 100 kg P2 = 100 kg P3 = 125 kg With angles above Technology and Reenginerring

  47. Setting and dividing energy graphically and analitically grafically Conclussion : • Decide energy scales for instance 1 cm = 25 kg. • Illustrate energy position with scaling.

  48. Setting and dividing energy graphically and analitically grafically 5. Make a paralelogram with R1 and P3 as its side. 6.Pull diagonally from the angle R1 and P3 and to be R 7. Decide R length then multiplied with energy scale and that’s R Technology and Reenginerring

  49. Setting and dividing energy graphically and analitically grafically See this picture : R = 10,2 cm x 25 = 280 kg If there are many energies, so the way used is the The same with above. Technology and Reenginerring

  50. Setting and dividing energy graphically and analitically • Arranging energy with poligon Deciding resultante with poligon, we only connect one energy with the other, then the connector of the first work line with the last one, then we called it resultante (R). Otherwise, it move to the last energy. Technology and Reenginerring
