it would be a bc its a sqare?well 3d is like you can say a cube 2d is like flat
Explanation:
Answer:
The number of threads in a worm is the number of teeth in a worm. The speed transmission ratio of a worm and worm gear set is obtained by dividing the number of teeth of the worm gear by the number of threads of the worm.
Answer:
The maximum length of the specimen before the deformation was 358 mm or 0.358 m.
Explanation:
The specific deformation ε for the material is:
(1)
Where δL and L represent the elongation and initial length respectively. From the HOOK's law we also now that for a linear deformation, the deformation and the normal stress applied relation can be written as:
(2)
Where E represents the elasticity modulus. By combining equations (1) and (2) in the following form:

So by calculating ε then will be possible to find L. The normal stress σ is computing with the applied force F and the cross-sectional area A:



Then de specific defotmation:

Finally the maximum specimen lenght for a elongation 0f 0.45 mm is:

Answer:
, 
Explanation:
Since man and river report constant speeds and velocities are mutually perpendicullar, the absolute speed of the man is calculated by the Pythagorean Theorem:


The required time to make the crossing is:
