Pulleys can be helpful because they provide a mechanical advantage, allowing for easier lifting of heavy objects by distributing the force needed over multiple ropes or cables. They also allow for changes in the direction of force, enabling more flexibility in moving objects. Lastly, pulleys can help in lifting objects to higher heights by reducing the amount of effort required.
Yes, a pulley can change the direction of a force. By using a pulley system, a force applied in one direction can be redirected to move in a different direction. This is helpful in many mechanical systems for changing the direction of motion or the orientation of loads.
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
The driver pulley is the pulley connected to the power source (like a motor), while the driven pulley is connected to the driven load (like a conveyor belt). The driver pulley transfers rotational force to the driven pulley through a belt or chain, allowing the load to be moved or operated.
none of them are the least helpful they all help things move upward except the lever but the most helpful one is the pulley a pulley takes up less space and it goes straight up so u can use less force
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.
Either someone has used a belt dressing that left a residue on the pulley or there is a bearing oil seal leaking in the vicinity of the pulley. A few more details of the pulley's environment would be helpful.
Most bolts turn counterclockwise to come off. Year, make, model and which pulley would be helpful.
Yes, because with an extra hand they don't need to make a ladder
Have you ever seen an old fashion water well, the kind with a bucket? The bucket is raised and lowered by a rope on a single pulley.
A rope, cable, string, or belt can be very helpful.
A pulley. Helpful? If it was, click yes, if not, click no, and of course, you don't have to.

There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
