A. Q4 A piston of cross-sectional area a is used in a hydraulic press to exert a small force of magnitude f on the enclosed liquid. A connecting pipe leads to a larger piston of cross-sectional area A (Fig.14-36).(a) What force magnitude F will the larger piston sustain without moving? (b) If the piston diameters are 3.80 cm and 53.0 cm, what force magnitude on the small piston will balance a 20.0. larg piston -> Small piston a
Please answer the following with detailed and clear explanation. An open tank in the shape of a frustum of a cone is bound by two hoops, one at the top and the other at the bottom. The diameters at the top and bottom are 2m and 3m, respectively. If the total bursting force is to be taken care of by the hoops, find tension in each hoop if water stands 2 m in the tank. Height of tank is 3.0 m.
