Project #15: Make Homemade Glue from Milk With milk‚ white vinegar and baking soda‚ you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster‚ or work on different materials (wood vs. plastic vs. paper).

VW Spot-Weldable Strain Gauge Designed to measure strain in steel‚ this vibrating wire strain gauge is spot-welded to the surface of the steel. A sensor is then fixed atop the gauge. Readings are obtained with a VW readout or with a data logger. Advantages: Patented low-profile design reduces errors caused by bending. Spot welding

too much evidence that supports Cecil killing Moose with wire to be able to ignore the option. Cecil was known around the camp for his capability to create trinkets for the other men with wire. He was asked by Mr. Anderson‚ one of the camp leaders‚ to make him a watch strap‚ who also voiced his concerns about him running out of wire. Cecil responded by saying " I still have enough

Suppose a current-carrying wire has a cross-sectional area that gradually becomes smaller along the wire‚ so that the wire has the shape of a very long cone. How does the drift speed vary along the wire? (a) It slows down as the cross section becomes smaller. (b) It speeds up as the cross section becomes smaller. (c) It doesn’t change. (d) More information is needed

TRANSFORMER PROJECT You can make a transformer from magnet wire and an iron rod. Remember that magnet wire‚ although it looks bare‚ actually has an enamel coating on the outside that serves as insulation. Enamel is used on magnet wire so that the insulation is very thin and the coil of wire can be compacted into a smaller space‚ thus enhancing the inductive phenomenon. small gauge wire and cause it to melt‚ which is a very good example of how a fuse works‚ but could cause you to

to conduct electricity. 7. How should the resistances be connected so that the equivalent resistance is increased? (1 Mark) (Ans) The resistances should be connected in series so that the equivalent resistance is increased. 8. The length of the wire is doubled‚ what is the change in its resistivity? (1 Mark) (Ans) There is no change in the resistivity since it only depends upon the type of material used. 9. The combination of resistances shown below has equivalent resistance equal to 12

Connect one end of the white wire to one of the nails and then place the nail into one half of the potato. 3. Connect the other end of the white wire to the battery holder inside the digital clock. 4. Connect one of the pennies to one end of the black wire then put the penny into the same

does the length of wire and thickness of wire affect the efficiency of Atwood’s machine?” NAME: MUHAMMAD HARIZ BIN MD YUSUF MAY SESSION 2013 CANDIDATE NUMBER: 002348-086 CENTRE: MARA COLLEGE SEREMBAN‚ JALAN AMINUDDIN BAKI‚ 70100 SEREMBAN‚ NEGERI SEMBILAN‚ MALAYSIA. NUMBER OF WORDS: 3592 NUMBER OF PAGES: 34 Abstract The thickness and the length of wire are the properties which affect the efficiency of pulley system. To find out the best length and thickness of wire and rope that suitable

which is often a piece of wire‚ must be perpendicular to the magnetic lines of force in order to produce the maximum force on the free electrons. The direction that the induced current flows is determined by the direction of the lines of force and by the direction the wire is moving in the field. In the animation above the ammeter (the instrument used to measure current) indicates when there is current in the conductor. If an AC current is fed through a piece of wire‚ the electromagnetic field

conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance.
