Difficulty in understanding electric heater Q relating to its power
Right now, you are given power and time, which allows you to work out $Q_{electric}$.
$$Q_{electric} = P \ t$$
In the real world, you would require the conversion efficiency, but you are not given tha …

Resultant of forces
It's because of the way the Law of Cosines works. They get the answer in one calculation.
If you know $a$, $b$, and angle in between them $\gamma$, then you will get c. The magnitude to complete the …

Reading stepper motor datasheets to get torque and speed
You are considering it from an electrical engineering perspective. Speed vs torque. It's more a digital motor with a rotor position that can be easily controlled (read head on floppy drives).
It is …

Trouble with an actuator on a Robotics SolidWorks design. Any ideas why?
Mate edges in Blue in parallel. Same for edges in Red.
Then you can mate circular plate to actuators.
The why comes more from the idiosyncrasies of how SolidWorks works than how someone visualizes h …
