Final Answer:
The 1880kg pile driver is used to drive a is Wedge.
Thus option d is correct.
Step-by-step explanation:
A pile driver is a heavy tool used in construction to drive piles or poles into the ground. It operates on the principle of converting a large force over a small distance into a smaller force over a larger distance. When the pile driver strikes the top of the pile, it delivers a substantial force over a small area, effectively driving the pile into the ground. This process involves the use of a wedge, which is a simple machine.
Wedges are used to separate or lift objects apart by applying force to the narrower end of the wedge, converting it into a larger force over a wider area. In the case of driving piles, the pile driver essentially functions as a massive wedge. The weight of the pile driver produces a considerable force when it strikes the pile, concentrating that force onto a small surface area, allowing it to penetrate the ground.
While nails, screws, and bolts are fasteners used for joining materials, a pile driver, with its heavy weight and force, is specifically designed to drive piles or stakes into the ground. This action requires a tool that can generate significant force over a small area, making the wedge shape of the pile driver an ideal tool for this purpose.
Therefore option d is correct.
