1. ### Calculating bolt size required to prevent beam bending

The attachment shows a side section of a water tank.(lined with Marine Ply) The section will be bolted to a fixed bottom section with 4 bolts. I'm trying to determine the size and strength of bolts required to do this. My attempt at starting this problem is shown in the attachment...
2. ### Help calulating bolt strength to prevent beam bending

Homework Statement The attachment shows a side section of a water tank.(lined with Marine Ply) The section will be bolted to a fixed bottom section with 4 bolts. I'm trying to determine the size and strength of bolts required to do this. Homework Equations Hydrostatic force? UDL...
3. ### Hydrostatic force acting on beam

Attached is the problem i am trying to get to grips with along with my current line of understanding, The column seen is a side section slice from the design of a water tank. The column is designed to take the load of the water. The column is designed with 2 unequal angle 75x50x6 steel...
4. ### Help calculating power required to drive shaft

Homework Statement Calculate the motor size required to drive shaft A. (shown in schematic 1 diagram) Drive shaft rotates at 75 Rpm. Weight of plunger + attachments = 30kg's Dimensions of plunger given in schematic 2. Homework Equations Work done = F x d (distance...
5. ### Calculating pressure acting on sides of tank

Homework Statement Tank is 10m x 1m x 1m Tank is full of water. What is the maximum pressure acting on the Tank? What is the maximum force acting on the sides of the tank which could cause bending of the tank? Homework Equations Pressure = l*g*h where P = water pressure (hydrostatic) l =...
6. ### Calculating force to displace water

I am trying to determine the force required to displace water as shown in the attached picture. My problems here are that I am displacing water using a vertical plunger moving downward at 25cm/sec also as seen in the picture the plunger is at 45degrees. I am confused as to how to calculate...
7. ### Dual shaft right angle gearbox

I'm looking for a right angled dual output shaft gearbox like the one attached I cant find one anywhere, just parallel dual shaft gearboxes. Anyone know a supplier or website for these? Do they even exist?
8. ### Determining power requirements for an AC Motor

I am trying to determine the power requirements for an AC Motor for a Plunger type wave maker. Attached is the layout of the plunger and tank. The formulas that I think might be involved in solving this problem are below: P.E = mgh W= F x d Power= W/time Pressure= F/ area What I...
9. ### Force required to produce wave in tank

Homework Statement I am building a tank to produce waves. I have two options to power the flap that will be produced to create the waves: 1. Pneumatic system 2. Motor and Cam system Before I can order motors or pneumatic air cylinders I need to know what force will be required to move...
10. ### Finding Wavelength and Velocity of an Ocean Wave.

Homework Statement Find Wavelength and Velocity of an Ocean Wave. Known Variables: Water Depth=300m Frequency=8secs Amplitude=3m Homework Equations Wavelength (m) X Frequency (s-1) = velocity (m/s) v=velocity The Attempt at a Solution I have 2 missing variables for both...
11. ### Design of Wave generator mechanism

Attached is a drawing of my Proposed mechanism. Am I right to say the period of the waves could be determined by changing the length of the Rod? Any comments on the design?
12. ### Scaling a Wave Tank

I am doing a project to build a scaled wave tank. "This project involves the design, construction and testing of a wave tank. When studying the hydrodynamics of a scale model or prototype, it is important to choose an appropriate scale. To determine tank and wave dimensions it is necessary to...
