tension here is acting in direction of effort
But should not it act opposite direction
tension here is acting in direction of effortAsked by lovemaan5500 | 8th Dec, 2017, 12:59: PM
Expert Answer:
Tension in the string is reaction force due to gravitational forces load and pully. Hence it will be in the opposite direction of gravitational force due to load and pully.

- the velocity ratio of block and tackle system of police 9 if its efficiency is 95% done by applying an effort of 250 Newton what maximum load can be lifted by pulley system
- what is the First Method Of Combination Of Pulley ?
- ex. 3b numerical 11
- ex. 3b numerical 10
- 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?
- Combination of pulleys
- A pully system with V.R. = 4 is used to lift a load of 175 kgf through a vertical height of 15m. The effort required is 50 kgf in the downword direction.(g= 10N/kg) Calculate: (1) Distance moved by the effort. (2) work done by the effort. (3) M.A. of the pully system. (4) efficiancy of the pully.
- (ii) Why should the lower block of this pulley system be of negligible weight?
- Design a pulley with M.A. 5 and V.R. 4 AND IT IS POSSIBLE TO MAKE THIS KIND OF PULLEY SYSTEM.BUT I DON'T KNOW HOW TO??
