Hi all not sure if I am posting in the right place need some help for the life of me I can not work out the answer for the question. Any advice or corrections would help massively.will attach a two pictures one showing question and the other showing my answer.

thanks, nick

The problem image is too small to read. One way to avoid that is to display the original image at a good size on your computer and use the "clipping tool" or similar screen shot tool to make an image. Also, be sure to preview your post before submitting.

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. 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.
Dimensions are: L = 1.25m, H = 0.6m & W = 0.5m




When the tank is full of water:

1. Calculate the size and location of the water thrust force on side A
2. Draw a side on view of side A (looking along arrow D shown) and show the size of the two forces acting on the tank side and how high they are located from the bottom of the tank
3. Calculate the required resisting force at the clasp to keep the panel shut.

c being the one i am having problems with

equation is clasp force x.6 = thrust force x .2

thrust force = 2.205kn

2.205 x .2 = 4.410kn

4.410kn x .6 = 26.46kn

which is wrong am i right in saying

i should dived by .6?

and the answer should be 0.735kn???

Calculate the required resisting force at the clasp to keep the panel shut


clasp force x.6 = 2.205kn x.2

my answer

4.410kn x .6 = 2646kn

but this wrong should it be

4.410kn / .6 = 7.35kn
