Block and tackle diagram

A block and tackle system has the velocity ratio 3. Draw a labelled diagram of the system indicating the points of application and the directions of load L and effort E. A man can exert a pull of 200 kgf. (a) What is the maximum load he can raise with this pulley system if its efficiency is 60%? (b) If the effort end moves a distance 60 cm, what distance does the load move?

Block and tackle diagram. 8-PART BLOCK AND TACKLE • Working load of 19,000 lb @ 5:1 safety factor • Standard 150-ft of 9/16-in Samson Tenex line (13,500 lb break strength) • Total weight including 150' of line = 61 lbs • Precision sealed ball bearings to reduce friction • Comes complete with 2 x 7/8" shackles with working load of 19,000 lb By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle. Diagram 3: The gun tackle "rove to advantage" has the rope attached to the moving pulley. Like most other window balances, block and tackle balances are located in the window jamb. This device includes a combination of two or more pulleys, a cord, and a spring contained within a "U" frame channel. The "U" frame is a long square container with one open side (pictured above). Some block and tackle systems also have "wings ... A block and tackle system has velocity ratio 3 . Draw a labelled diagram of system indicating the point of application and direction of load and effort. A man can exert a pull of 200 kgf. a) what is maximum load he can raise with this pulley system if its efficiency is 60%? b) if effort end moves a distance 60 cm,what distance does the load move?

An assembly of blocks with a rope threaded through the pulleys is called tackle. A block and tackle system amplifies the tension force in the rope to lift heavy loads. They are common on boats and sailing ships, where tasks are often performed manually. In the diagram on the right, the number of rope sections of the tackles shown is as follows: To determine total load on block E: E = 500 lbs. x .84 = 420 lbs. (line pull) (Factor 130° angle) To determine total load on block F: F = 500 lbs. x 1.41 = 705 lbs. (line pull) (Factor 90° angle) The Reeving of Tackle Blocks In reeving of tackle blocks, there are many methods. The method discussed below is referred to as "Right Angle ... Total Block Load: Upper Block (LBS.) Lower Block (LBS.) Working Load Limit for Crosby Blocks indicates the maximum load that should be exerted on the block and its connecting fitting. A single sheave block used to change load line direction can be subjected to total loads greatly different from the weight being lifted or pulled. A block and tackle pulley system has a velocity ratio 3. i) Draw a labelled diagram of this system. In your diagram, indicate clearly the points of application and the direction of the load and effort. ii) Why should the lower block of this pulley system be of negligible weight.

How a Block and Tackle Works. A simple pulley system. ­­If you have ever looked at the end of a crane, or if you have ever used an engine hoist or a come-along, or if you have ever looked at the rigging on a sailboat, then you have seen a block and tackle at work. A block and tackle is an arrangement of rope and pulleys that allows you to ...

By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle. Diagram 3: The gun tackle "rove to advantage" has the rope attached to the moving pulley.
