This document discusses the design and specifications of a pedal-powered washing machine. It includes calculations showing that the gear system provides a torque of 75N-m and rpm of 38 on the pedals, increasing to 304 rpm on the output shaft, providing 8 times the input rpm. It also notes the social impacts of providing electricity-free washing, and lists a budget of Rs. 6.25 lakhs for the project costs including technology development, testing, and machinery hiring fees.

4. TECHNOLOGY
Average pedal fore F1=156.5N
Also, for 1.5 kg of cloths,F2=1.5*g =1.5*10N =150
Total pedal force, F=F1+F2 = 156.5+150 =306.5 =300N (approx.)
Torque T=F*r = 300*0.25 =75N-m
Power ,P =300 …………(power during cycling is between 250 to 500 W)
P =2*Pi*Np*T/60
or, 300=2*pi*Np*75/60
or, Np=38.197rpm=38rpm (actual rpm produced by pedaling)
In our demonstrative model , we have
number of teeth on pedal gear,Tp=60
number of teeth on sprocket,Ts=30
Gear Ratio=Tp/Ts=60/30=2
Also,we know that Np*Tp = Ns*Ts
or, 38*60=Ns*30
or,Ns=76 rpm

5. TECHNOLOGY…
The same rpm is transmitted to the compound gear G1,N1=76rpm
Also, teeth on compound gear G1, T1=120
teeth on intermediate gear G2, T2 =90
teeth on small gear G3, T3=30
rpm of intermediate gear G2,
N2*T2=N1*T1
or, N2*90=76*120
or, N2=101.33rpm
rpm of small gear G3,
N3*T3=N2*T2
or, N3*30=101.33*90
or, N3=304 rpm
Hence , we get 304 rpm on the small gear shaft on which drum is
mounted.
N3/Ns=304/38 =8 times
So , we get 8 times of input rpm on the output shaft.

6. SOCIAL IMPACT
 A pedal-powered washing machine would allow
women to wash clothes faster and with less strain
 It also emphasize on physical exercise of human
body
 The target population for the innovation will be
the villagers of India because 35.5% of the
population still live without access to electricity
 Lesser maintenance required
 Zero operating cost
 Very effective in protecting the hands of washer
men

7. UNIQUENESS
The horizontal axis pedal powered washing machine has
following uniqueness like-
1.Minimized human effort in pedaling by applying gear and
pinion arrangement.
2. Works without electricity so it can be an ideal machine for the
people in the electricity deficient Indian villages.
3. Horizontal axis pedal washing machine consumes less
power as compared to vertical axis washing machine.
4. It encourages pedaling which is a good physical exercise
and keeps oneself fit.
