ANSWER ON THE PINK PAGES The tail lift of a truck is hinged to the undercarriage at point A. A piston BC is attached at point B. Both at the top (point B) and at the bottom (point C), the piston is connected via a pin connection to the tail lift and the undercarriage, respectively. The distance between points A and B is 2.00m; the distance between points A and C is 2.5m. The distances between the pins in A and B and the tail lift may be neglected. A refrigerator (100kg), with a width of 1.50m and a height of 2.00m, is placed centrally in relation to point B. To unload the refrigerator, the tailgate is placed at an angle a. The whole process is carried out very slow, so dynamic effects can be neglected for the requested calculations. 2,00m 1,50m 2,00m A 100 kg ja 2,50 m B Questions, also draw all relevant free-body diagrams The drawn free-body diagram(s) should be completed and all vectors should be assigned with the right direction. a) Calculate the angle a (between the tail lift and the horizontal direction) above which the refrigerato will tip over. b) What is the maximum allowed (static) coefficient of friction between the refrigerator and the tail li to ensure that the refrigerator will slide down instead of tipping over? c) Will the maximum allowable coefficient of friction, calculated in question b), increase, decrease remain the same as the weight of the refrigerator increases? Justify your answer. ANSWER ON THE PINK PAGES The tail lift of a truck is hinged to the undercarriage at point A. A piston BC is attached at point B.
