Use a come along by extending the cable to its full length, attaching one end to a stationary object and the other to the load. Move the handle back and forth until the device rewinds the cable on the central wheel. To continue to move the load, extend the cable again and move the stationary end to a new anchor point.Know More
A come along is a hand winch that allows a human to move a heavy load using a system of levers, pulleys and cables. Farmers often use the device to tighten wire when building fences. In the garden, it is useful for heavier jobs such as removing tree roots. The device allows a user to exert 2 to 10 tons of force on the object being moved.
The come along uses a lever and a ratcheting wheel to rewind the cable. The cable attaches to the come along frame and to the ratcheting wheel with a pulley at the end that attaches to the load. This arrangement creates a movable pulley, giving the user a mechanical advantage by dividing the force to move the load by one-half. The handle of the come along is a second-class lever, with the bolt in the center of the wheel acting as the fulcrum and placing the load between the fulcrum and the force, at the edge of the wheel. The length of the lever determines the amount of additional mechanical advantages it provides.Learn more in Tools
To make a simple pulley, stick wire through an empty thread spool such that the spool can spin freely and attach the wire to a stationary object, then tie a small object such as a toy or pencil to a string and run the string from the ground up around the spool and back down to the small object. This will create a simple pulley system, where the string can be pulled down to lift the small object up towards the spinning thread spool.Full Answer >
A static force refers to a constant force applied to a stationary object. A static force is too weak to move an object because it is being countered by equally strong opposite forces.Full Answer >
Static balance refers to the ability of a stationary object to balance. It happens when the object’s center of gravity is on the axis of rotation. Dynamic balance, on the other hand, is the ability of an object to balance while in motion or switching between positions. In humans, both types of balance are necessary to ensure an active lifestyle.Full Answer >
To wear a sari in the Gujarati way, a petticoat and blouse are needed; the top plain portion of the sari is tucked inside the petticoat slightly to the right of the navel, keeping the full length of the fabric on the left-hand side of the body, and the lower end of the sari should touch the floor. Traditional regional methods usually dictate the way a sari is worn.Full Answer >
