conceptual desing for the cart

The designed freight train is 250 long, 100mm wide and 119mm high. Every component provided has been put into use, 2 motor, all eight gears and the chain.

The maximum torque which can be provided by the one motor is 60g-cm this translate to 0.588N-cm. so for the two gears = 1.176N-cm

Maximum ballast;

If we could use 0.5N-cm from every motor and the wheels has radius of 16mm

Torque= force * radius

0.5= 1.6cm* F

So the two motors can support 320*2= 640g

The largest gear will be connected to the motor which is then connected to second largest gear.

Speed of gear;

conceptual desing for the cart  1=conceptual desing for the cart  2

conceptual desing for the cart  3=conceptual desing for the cart  4

conceptual desing for the cart  5=1453.3rpm

Since gear two and three are connected directly,
conceptual desing for the cart  6

Speed of gear = speed of the wheels

conceptual desing for the cart  7=conceptual desing for the cart  8

conceptual desing for the cart  91090rpm

Velocity ratio=
conceptual desing for the cart  10=2

Mechanical advantage =
conceptual desing for the cart  11 =
conceptual desing for the cart  12

Efficiency=
conceptual desing for the cart  13

=
conceptual desing for the cart  14 x 100%

Velocity of wheels

wheel= 1090rpm

=conceptual desing for the cart  15 * 1090

= 114.14 rad / sec

= 1.83m/s

Time taken to cover the 5m

=conceptual desing for the cart  16

= 2.74 seconds
