In horizontal applications, where the load is supported by a low-friction linear guide, the weight of the moved load contributes only a small amount to the axial load on the screw. But in vertical applications, where gravity causes the screw shaft to see the full force of the load, buckling can become a significant factor in lead screw sizing.

Lead screws are based on metal-to-metal contacts. That limits their efficiency to between 10% and 70%. In some cases, this can be beneficial. If the screw pitch is less than 0.125 inches per revolution, the lead screw becomes self locking. This means that even in a vertical application, it will not move unless it is powered by the motor.
Non-Conventional Dice Roller. Use the following virtual dice roller to mimic dice that have a different number of faces from the conventional 6-faced die. The most common physical dice have 4, 6, 8, 10, 12, and 20 faces respectively, with 6-faced die comprising the majority of dice.

Textbook roller coasters loops are often drawn as circles with the train entering and exiting the loop on horizontal tracks, like in figure 2. This shape would lead to an abrupt change in acceleration (i.e. a large jerk [7, 8]), with the sudden change of radius of curvature. (The lettering in the exam problem was chosen to indicate the train ...

Lead screws are better for vertical applications. Lead screws are generally less efficient, requiring greater torque and a larger motor and drive. Lead screws have higher friction and run a hotter temperature. Most lead screws are not well suited to high throughput, high speed applications or those with continuous or long cycle times.
