Maori saftey signs

 Hello everyone today I am going to make a blog about safety signs in Maori to celebrate Maori language week so here are some safety signs in Maori if you would like me to add some more you can tell me in the comments or what signs you would like to see. Tena, Katia Te keti this means stop or this area is restricted.

Metal drill bits

 Yr 9 Term 3 Drill bits.

 

Answer the following questions using this doc  https://drive.google.com/file/d/0B_C_XhcwQPsxZXVmQi1zLUtTV2pjTmcwek84Q2gxX3g5WXQ0/view?usp=sharing&resourcekey=0-zs9pvvfUCjJfDoET8gF6iA

Question 1 Parts of a drill bit

Question 2. What are the twist drills made from

Question 3. List the 4 points needed for a correctly grounded drill cutting edge reason: so it can drill through the metal. Land reason: so the land helps support the cutting edge and the rest of the parts of the twist drill it’s pretty much the body.

Question 4. What lubricant is required for mild steel and aluminum

Question 5. How are drills identified? Wood Drill Bits: These can be identified by a small, pointed tip at the very end. If you look closely, you can see spurs on each side. 

Masonry Drill Bits: These bits have a gently sloping tip. 

Metal Drill Bits: These have a wide-angled point at the end, and they may also be painted black.

Question 6. Draw a morse taper drill shank 

Question 7. What is a countersink drill used for? Countersinks are mainly used for countersinking drill holes, countersinking screws, and deburring.

Question 8. Redraw the countersink drill and the hole in its drills

Question 9. Describe the steps needed when drilling large holes or drilling accurately.

Question 10. Redraw the diagram showing marking out for a general hole. This is the information that I found about drill bits

Current electricity

 1. What is the particle that moves in a wire? Electric current is a flow of electrical charge. The electricity that is conducted through copper wires in your home consists of moving electrons.

2. If there is a high current in a circuit what does this mean? With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time 

3. How does electricity work to heat up a stove? How an electrical stove works is through a set of coils that are either exposed outside or inside.

4. Where is DC electricity used? Where is AC electricity used? AC power typically used a high power and long-distance transmission.

Stactic eletricity

 1. What are the 3 particles that makeup everything? Which ones have a positive and negative charge?

: Electrons protons  neutrons 

2. Objects want to be "electrically neutral" What does this mean A proton and an electron have an equal amount but an opposite type of charge.  

3. When you rub two so insulators and a conductor? When two insulators are rubbed together then they become electrically charged.

4. What is an example of static energy? when you put your hands on an electric fence or something like that you get a shock and get then your hair goes up because all of the electrons go up into your body.
