Why square threads are used in a screw jack?
§ Screw threads have better compression strength than other threads. § Due to low thread angle there is no radial pressure on nut. § Due to smaller angle, the lead of screw is less.
Why threads are provided in simple screw jack Give reasons?
Threads are provided in a simple screw jack to allow the movement to be calculated to a certain distance or height and to allow for less effort in lift.
What is the function of a simple machine lever?
to make your work easier . to less the working time
He developed a mechanical reaper in 1831?
Because it made work so much easier for the common reaper easier, making less work on the fields so it wouldn't take all day to rape yourcrops
What would the head pressure do if the fan motor on an air-cooled condenser stopped working?
The head pressure and compressor current would normally rise (strong winds and/or rain and/or very low air temperatures will reduce this effect). Less heat would be removed from the refrigerant and therefore deliver less cooling.
Is a screw with fewer or more threads per centimeter easier to drive a piece or wood?

Why might it take less force to unscrew a screw from a piece of wood than it did to screw it in?
It may take less force to unscrew a screw because when you were screwing it in, you might have overtightened it or created more friction between the screw threads and the wood. This can make it easier to break the initial resistance and unscrew the screw compared to when you were driving it in.

How is a screw related to an inclined plane?
On a screw, the threads are basically inclined planes, but facing down to help guide the screw into the wood. Using the inclined plane on the threads increases the time it takes rather than a nail, but it takes less energy to do it.
What are the Limitations of screw pitch gauge?
Some limitations of screw pitch gauges include difficulty in measuring certain types of threads, such as very fine or very coarse threads, inaccurate measurements if the gauge is not aligned properly with the threads, and potential wear of the gauge over time leading to less accurate readings.
Why do you think overcoming a resistance force using a screw is so easy?
Overcoming resistance using a screw is easier due to the mechanical advantage provided by the threaded design of the screw. The threads of the screw convert rotational force into linear force, allowing for greater force to be exerted to overcome resistance with less effort. This design also enables precise control and adjustment during the application of force.
How does a screw make work easier?
A screw is a simple machine that allows for the transfer of force over a longer distance, making it easier to apply a greater force with less effort. By twisting the screw, the rotational motion is converted into linear motion, enabling it to move objects with less force compared to lifting or pushing directly.
How is the mechanical advantage determined for a screw?
The mechanical advantage of a screw is determined by comparing the distance traveled along the screw's threads to the force applied to turn the screw. It is calculated as the ratio of the circumference of the screw to the pitch of the screw thread. A higher mechanical advantage indicates that less force is needed to lift a load.
Why screw is more easy to use a nail?
It isn't easier, it has more holding power, less chance of loosening.
