Machines are ubiquitous and can make routine jobs easier, such as the lifting and transporting of heavy goods. Tell me, have you ever pushed a wheelbarrow? Did you ever think about how much simpler it would be to move rocks or dirt if you didn’t have to do it by hand?
A wheelbarrow is superior to a shovel for moving bulky objects because of its straightforward design. When something is too heavy to move by hand, hydraulic devices can help.
Pascal’s Law is the foundation of a Hydraulic Lift’s operation.
Pascal’s law states that if any force is applied to any point of a confined fluid, then the pressure is transmitted undiminished and equally throughout the liquid.
Concept:
Hydraulic systems function by relocating fluids, such as the water in the syringes. There is no way to reduce the volume of a liquid. Fill one of the syringes with water, cover the opening with your finger, and try to depress the plunger to see if it works. Do you think you could move it?
If the hole is blocked, the plunger cannot be pushed down, regardless of how hard or how much weight is put on it. This awesome fluid feature is what makes hydraulic technology possible and what allows you to move large items with much less force than would otherwise be required.
Materials:
Cardboard
Knife box
Ruler
2 small oral syringes (10-25 mL or CC)
Tubes made of bendable plastic (can be found in hobby stores or medical supplies)
Water
Food colouring
Hot glue gun
Make Sure of adult supervision during the procedure.
Procedure:
Construct the lift’s housing first. Make sure the panels are of the same size by using the ruler. These measurements are a rough estimate; the size of your syringe will determine the final result. A base (13cm x 13cm), two tabs (1cm x 4cm) for inserting the syringe, and a lid (13cm x 13cm) should also be cut out.
Carefully use the box knife to cut off each of the cardboard pieces after you’ve measured them. In some cases, having an adult do this action may be necessary.
Make a little notch in the centre of one of the short edges of one of your panels (the 4cm x 13cm pieces).
It’s time to go on to the following few steps, which include using hot glue, which, as the name suggests, may get quite hot. Make sure an adult is helping you out so you don’t accidentally burn yourself.
Glue one of the panels to the bottom, the short side down (but not the one with the notches). After that, adhere the first panel and the base to the other two panels without notches. A three-sided rectangular prism, resembling a skyscraper, should materialise before your eyes.
Apply glue to the two tabs and attach them to the “wings” of a syringe. The movie up top does a great job of demonstrating this, so check it out if you need a visual.
These tabs will be glued into the lift housing once construction has begun. Verify that the syringe’s plunger is fully inserted into the syringe. Glue the tabs an inch or so below the panels’ apexes so that the plunger’s flat side rests on them.
Remove the syringe from the lift’s housing, and then connect one end of the transparent plastic tubing to the syringe.
Attach the panel with the notches using glue to complete the housing. Following the video’s demonstration, the notch must be precisely positioned above the tube.
You can bond the platform in place by placing a little amount of glue on the plunger’s flat surface (8cm x 8cm piece).
To make a colourful mixture, add a few drops of food colouring to the water in a bowl and mix. The coloured water should be drawn into the other syringe as much as possible by drawing the plunger up.
You can now utilise your hydraulic lift by connecting the other end of the plastic tube to the empty syringe. To inject liquid into the syringe fixed inside the lift’s housing, simply depress the syringe’s plunger. How successful was it? Has your tier risen? See how far you can push your lifting capacity by progressively bigger loads. Which features stand out to you?
A child’s insatiable curiosity can produce wonders; all we need to do is guide it in the correct direction. Your child can broaden their knowledge with the aid of Xperimentor science kits, which provide a home laboratory for scientific study. We want to open up science to everyone. Our hybrid science learning ecosystem serves as the Swiss Army Knife of efficient learning in this regard. With a tonne of entertaining science experiments, activities, and projects, it helps your child study at their speed while building solid core knowledge. We think that a new generation of scientists and inventors may emerge from the hands-on learning provided by our science experiment kits. It makes sense why kids adore it and why educators in all schools support it.
