Overview

Considering the balance and playability of the game, we have introduced scientific contraption stress. The kinematics calculates stress effects based on the number of working parts above and the number of blocks and swept area.

The stress is divided into two parts, the stress required for movement to overcome resistance and the stress required for the working machines to work.

The stress effect required for the work of the working element is the sum of the stress effects of all the working elements above. The working machines includes saws, harvesters, machine plows, etc., but does not include gears, rods and other equipment that do not move on the moving mechanism.

Movement overcoming drag effects is calculated by the number of blocks, and the stress consumption of blocks attached to other blocks without collision boxes is halved.

Linear Motion Mechanism

Linear motion mechanism refers to a motion mechanism whose moving track is a straight line, such as a rope pulley, a piston, a crane, etc.

The stress effect of the linear motion mechanism to overcome the resistance is

S = k ( N + n/2 ) +C

where s is the total stress effect;

k is one-fifth of the stress consumption sum of a standard square of 1m³, which is 0.125;

N is the number of non-empty collision box blocks;

n is the number of empty collision box blocks;

C is the friction force of the main block of the kinematic mechanism, which is available for every different kinematic mechanism.

In particular, the rope pulley does not need to dissipate the stress effect of overcoming resistance when descending.

Circular Motion Mechanism

Circular motion mechanism refers to the motion mechanism whose motion track is circular arc, such as clockwork bearing, dynamic bearing, etc.

The calculation method of the arc motion mechanism is similar to the linear motion mechanism, but the stress required for each block to move depends on the volume it sweeps.

The stress effect of each block to overcome resistance is

s = (5/6)Kkπr

where s is the total stress effect of this block;

K is the influence of the box collision box, the non-empty collision box box is 1, and the empty collision box box influence is 1/2;

k is one-fifth of the stress consumption sum of a standard square sweeping 1m³, which is 0.125;

r is the distance from the box to the axis of the motion mechanism, not including the size of the axis;

The total stress effect of a circular motion mechanism overcoming resistance is

S = Σ s +C

where C is motion The friction force of the main block of the mechanism is available for each different kinematic mechanism.
