Pressure is inversely related to the area on which force is applied. As the needle has pointed edge the pressure would increase and so it would be easier to go through the cloth for sewing purpose
A needle has a small point that concentrates pressure on a small area of the balloon, making it easier to puncture the surface and burst it. In contrast, a finger has a larger surface area, distributing the force across a wider area when pressure is applied, which makes it less effective at bursting the balloon.
The flat side of an egg has a larger surface area, which distributes the force of impact more evenly, making it easier to break the shell. On the other hand, the pointed edge concentrates the force in a smaller area, making it harder to crack the shell without breaking it into pieces.
A needle will sink in water because it is denser than water. The buoyancy force acting on the needle is not enough to counteract its weight, causing it to sink.
Water has a much stronger surface tension than alcohol does. Because water molecules are highly polar, they have a relatively strong attraction for each other (as compared to the attraction that the molecules of most other liquids have for each other) and this creates a kind of limited solidity on the surface, called surface tension. The alcohol molecule is much less polar and has much less attraction for other alcohol molecules, and correspondingly less surface tension. It is the surface tension that can support a needle on the surface of the water, despite the fact that the needle is denser than water and is not buoyant enough to float.
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.

It is easier to pass a cable through the eye of a needle than for a rich man to enter into the kingdom of God.
Sewing clothes with a tipped needle is generally considered easier than using an untipped needle due to a few reasons: Thread guidance: The tip of a needle helps guide the thread through the fabric, making it easier to create accurate stitches. The pointed tip allows the needle to penetrate the fabric smoothly, reducing the risk of snagging or pulling. Fabric penetration: The sharp tip of a tipped needle easily pierces through the fabric fibers without damaging them. This allows for cleaner and more precise stitching, especially when working with delicate or tightly woven fabrics. Reduced effort: With a tipped needle, less force is required to push it through the fabric. The pointed tip efficiently cuts through the fibers, resulting in a smoother sewing process. This can be particularly beneficial when sewing thicker or tougher materials, as it reduces strain on the hand and minimizes the risk of bending or breaking the needle. Stitch quality: The use of a tipped needle often results in neater and more consistent stitches. The precise penetration of the fabric, combined with the needle's shape, helps maintain a uniform tension and stitch length, contributing to a professional finish. While there may be specific instances where an untipped needle is preferred, such as when working with heavy-duty materials or creating specialized decorative stitches, in general, a tipped needle offers greater ease and efficiency when sewing clothes.
because the curve, like an arch in a bridge, is sort of self supporting. the flatter it is the easier it is to break.
That is is easier for a camel to pass though the eye of a needle than for a rich man to get into the kingdom of heaven.
Hitting an egg on its flat side distributes the force over a larger area, reducing the pressure on any one point and making it easier for the shell to crack. On the other hand, hitting the pointed edge concentrates the force on a smaller area, making it harder to break the shell.

Not likely. It is easier for a camel to go through the eye of a needle than for a rich man to enter heaven.
Knitting always requires two needles. Crafting fabric with one instrument, generally means crocheting.
