Question

A hinged water storage is shown below. Its top side is denoted as C, the narrow side as B and the long side as A Liew. Side C Clasp Side B Side A Hinges View Assume water density is 1000 kg/m3 and gravity is 9.81 m/s2 Side A is hinged at the bottom edge and secured using a clasp at its top edge centre position. Dimensions are: L = 0.8m, H = 0.6m & W=0.4m When the tank is full of water. a) Calculate the size and location of the water thrust force on side A b) Draw a side on view looking along the red View arrow shown above. Show the position and direction of the Thrust Force (trying to open the door) and the Clasp Force (trying to keep the door shut). Show also the hinge (pivot). This diagram will be very useful when you let the clockwise moments equal the anti-clockwise moments in partc) c) Now that you have determined the thrust force and its location (distance from the pivot-hinge) use moments to calculate the opposing Clasp Force trying to keep the door shut
