Wanting to make a self propelled wheelbarrow type vehicle, wanting to figure out what size engine and hydrolic motor to power it.berkeman said:Welcome to the PF.
What is the context of your question? Is it for schoolwork? And is the 150 pound weight a total weight including the rider? Must be a light rider on a Fixie...?
Want to be remote controlled. And already have electronic seloniod, for thatMech_Engineer said:

So what I am building is a powered wheel to drive a wheelbarrow type vehicle that already has two fixed wheels in front, my power unit will mount behind and needs to have variable speed and steering up to 180 degrees and wireless remote control. I am using a variable displacement pump because I can control it with an electric actuator, and also use an electric motor to run a gear or sprocket for turning the power wheel.Mech_Engineer said:
Using common automotive remotes give easy control to the electric motors and the hydrolic pump provides the transmission and cluch allowing me to be not have to control engine speed.Inventermark said:
As a prop, will have a lightweight plastic cover that makes it appear to be a cow. I am trying to keep the weight very low to the ground to help with stability, would be interested in making it electric, but don't have much experience in that area, it will only need to operate for 3 min or less not sure of the size battery needed for that.Mech_Engineer said:
This torque is way too high. Show your work.Inventermark said:
Torque value is a measure of the amount of force required to rotate an object around an axis. It is typically measured in units of newton-meters (Nm) or foot-pounds (ft-lb).
To calculate torque value, you need to know the force applied and the distance from the axis of rotation. The formula is torque = force x distance. For example, if a force of 10 N is applied at a distance of 2 meters from the axis of rotation, the torque value would be 20 Nm.
Torque value is important in many scientific and engineering applications. It helps determine the strength and stability of structures and machines, and is crucial in designing and building effective tools and equipment.
Torque value can be measured using a torque wrench, which is a specialized tool that applies torque to a bolt or nut and measures the amount of force needed to tighten it. It can also be measured using a dynamometer, which measures the torque output of a rotating shaft.
Yes, there are different types of torque value depending on the type of force being applied. Some common types include static torque, which is a constant force applied to an object, and dynamic torque, which is a force that changes over time. There is also tightening torque, which is the amount of torque needed to tighten a fastener, and breakaway torque, which is the force required to break a bolt or nut loose.
