@XL83NL Could you please provide me with the calculation you have used to get 21.354? Thanks for the help...

@goutam_freelance Thanks for your help! I used the below calculation and got tube length L=152 meter OR 5972 inches! q=U A dT q= 1465355 W m2(5 million BTU) U= 28.15 watt/square meter/°C (Used std hi & ho for Heating air with saturated steam where as I use conventional burner) dT= 2150 °C (...

Hi, Air amount: 8000 CFM Burner temperature: 1800°F Furnace capacity: 5 million BTU Question: I want to heat up the air from 70°F to 150°F, If the air flowing through the 2" OD X .15"wall-thickness of Stainless steel tube what will be the tube length I should use? Thanks a lot!

Hello, I have extracted a surface from a solid CATIA file. Now I need flat pattern out of it. can anyone please help with this? Thanks, Gopal

@ SAITAETGrad I have confined space for the assembly, i would like to hear you idea about https://www.haacon.com/pageflip/hci/mobile/index.html#p=112

rb1957 Torque = Force X Distance is the basic formula. But i do want to calculate the torque for over hanging load with COG eccentric to Center of rotation!

we have proven this design with electrical motor and Hydraulic jacks But now we decided to increase overhanging distance and also wanted to move from electric and Hydraulic to Manual so i decided to go for Screw jacks for lifting and Gear drive for hand crank the whole structure looks like...

What if i am adding counter weight to match COG and COR?

@SAITAETGrad This is not for a School project! I am designing a tool to rotate and position the heavy equipment I am finding difficulties to calculate the torque for eccentric load of 680kg. The axis of rotation is horizontal and the distance between Center of mass and Center of rotation is...

Sorry for the in-proper information! Actually i need to rotate a heavy loaded fixture overhanging on an axis. And this one needs to be rotated by hand crank method. I calculated the maximum torque 1600 NM. And it is not a continuous rotation. I searched and found the Manual crank (Haacon Type...

Hi 3DDave I have chosen the Haacon Type 242.3 Manual crank to do this. Please give your comments Thanks!

Hi, I need a hand cranking methods to rotate by 1600NM. I was searching in Boston gears but unable to find out. The fixture rotation rpm is 0.5. Thanks!

Sorry about that. I was not clear. I am going to form 2024-T3 condition material. The sheet thickness is .063" and bend radius of .33"

Thanks rb1957, The material go only with T3 condition not going for T42. the bend radius is .33" i just need a joggle over the 20" sheet. i am wondering if i need to consider spring back on this part or no? Thanks

Hi, We have form blocks for 2024-0 condition material, now i need to design form block for 2024-t3 063"thk material. Please help me on points to be considered.Thanks!
