Auto/Motor Building a mini physics motor boat -- Help?

AI Thread Summary
The direction of propeller rotation, whether clockwise or counter-clockwise, does not significantly impact the speed or acceleration of a mini physics motor boat as long as it is designed to operate in that direction. The key factor is that the propeller must effectively displace water to create thrust. Both directions will generate a force that propels the boat forward by pushing water in the opposite direction. The discussion emphasizes understanding the mechanics of water displacement rather than focusing solely on rotational direction. Ultimately, the design and efficiency of the propeller are more critical than the rotation direction itself.

Should the propeller rotate clockwise or counter-clockwise? Which way will be faster and will allow the boat to accelerate the fastest?

What is the context for the question? Please supply many more details so we can try to help you. Is this problem for schoolwork?
 
It doesn't matter which way it rotates, as long as it's rotating in the direction it is designed for.
Either way it's forcing water molecules to move in one direction, so the boat moves in the other direction.
The water molecules don't care which direction the propeller spins, they only are experiencing a compression effect, so they move.
 

Thread 'Heating pad element sizing'

Three rabbits will be wintering in a 2m x 2m x 2m wooden hut. Outside temperature does not go below -30c (-22f) Planning to put a 50cm by 50cm 1mm thick stainless steel sheet on the floor of the hut (inside off course) My plan is to heat the sheet with a 50w PTC heater element https://fi.rsdelivers.com/product/dbk-enclosures/fg135600/dbk-enclosures-heating-element-75mm-50-w-100-240-v/dc/2995922?backToResults=1 Is this heater (50W) enough to keep the pad warm enough to sustain liquid...

Thread 'Determining Ramp Length for Ground Clearance'

Hey all. I'm looking to buy a zero-turn mower and I need to build/purchase a ramp to get it into my shed for storage. Exact model is this one. I need to figure out how long of a ramp I need to make sure the mower doesn't bottom out when driving up and down the ramp. Mower stats: Wheelbase: approximately 76 inches. Height: 4.5 inches (based off the highest setting on the deck height adjustment) Shed entrance is 12 inches off the ground. The manufacturer says that the mower can handle...

Thread 'How to remove a seized toilet tank bolt?'

greetings I replaced my bedroom toilet due to water leak and unable to replace water tank bolt with new ones. so now i have old toilet in the yard and i took a closer look at the seized bolt, it seems that the bottom part (a butterfly fastener) holds onto the bolt really tight, when i turned the head inside the tank with flathead screwdriver, the fastener moves with the bolt as the whole. is there a way to remove the bolt?
