I am a businessman having my shop in market I want to fix a safety door (shutter ) for my shop This shutter is of 1000 Kg and I don’t want a outside opening provision for this shutter (My labor’s can only open it from inside) I want to do this work in lowest possible cost. Design a proper pulley system for shutter door with inputs given on next side -

Cost per itemMass per item Pulley1000 rupees10 kg Multi- Pulley 2000 rupees20 kg Cost per metre Rope50 rupees Cost of electric winchPulling force of winch Winch6000 rupees2000 N Mass of Door Door1000 kg

3 Mechanical Advantage = Force Out (N) ÷ Force In (N) Weight (N) = Mass (kg) x gravitational force Mechanical Advantage = 2 x number of movable pulleys

Few options!

Keep cost of your design as less as possible - more pulleys or more winches? Find out different force Find out Mechanical Advantage Find out number of Pulleys required

4-5 students in one group Decide your team leader 10 mins for designing discussion 20 mins load calculation 30 mins design work – Door design, pulleys design 20 mins working on business pitch –Designing calculation, cost calculation ………..
