Calculating Maximum Angle for Incline w/ Stall

AI Thread Summary
To calculate the maximum angle for a vehicle moving up an incline, torque must equal the force required to overcome gravity at a standstill, which occurs when speed is zero. The equation Torque = r * F * sin(angle) can be used, but it’s essential to consider that at stall, the vehicle's speed is ideally zero. Incorporating torque/speed graphs can help visualize the relationship, especially since electric motors provide maximum torque at zero speed. Additionally, using a clutch or torque converter may be necessary to manage speed differences between the wheels and motor. Understanding the impact of friction on slope angles is also crucial for accurate calculations.

I want to calculate the maximum angle an object can move. So my example is a vehicle using two motors going up an incline. Do I use Torque = r * F * sin(angle) until the torque totals to a constant max torque value but with a speed of 0? I did think maybe I had to change values to equal the torque to 0, but if torque = 0 then from graphs, the speed is at a constant movement. And in the physical world, I want the speed to = 0 ideally so the object is in stalling (these are my assumptions).

I'm just not sure where I go next with this data. So any push in the right direction would be appreciated.

I have looked into torque / speed graphs, but I'm not 100% how to incorporate stall on an incline, so I assumed using the equation above would satisfy my question.

From the motor point of view, you will need a clutch or torque converter that will slip to accommodate the speed difference between the wheels and the motor. With an electric motor, there is no problem as it produces its maximum torque at zero speed.

For more info on the potential slope angle for a vehicle, but based on friction, see the section Theory»Longitudinal acceleration»Accelerating»Hill climbing at the bottom of the page on this http://hpwizard.com/car-performance.html" .

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
