I never even considered drag, but for this problem I would be happy to ignore its effect. Anyone got any Ideas?

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...

30 kg - 215kg = -185kg or 185 kg Multiplying this x 9.81 to get force = 1815N I am unsure what you mean here. What I did was make an integral for the Force with repsect to distance: ∫_0^xm▒( F)(x)dx =1815 [x^2/2]_0^(.6) =326.7 N "Add the amount of work it takes to get the block...

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...

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...

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 =...

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...

I'm looking for a right angled dual output shaft gearbox like the one attached I can't find one anywhere, just parallel dual shaft gearboxes. Anyone know a supplier or website for these? Do they even exist?

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...

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...

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...

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?
