Answer:
Torsional stress.
Explanation:
An item experiences torsional tension when it is twisted from one end. The molecules on an item's surface are tugged in various directions as the object is twisted, creating a twisting force or torque. As a result, the item experiences what is known as torsional stress. It is a kind of shear stress that has an impact on the material along the object's axis. The stiffness and strength of a material determine how much torsional stress an item can bear.

If an ellipse has a major axis of 10 cm.(2a) and an area (A) of 62.8 cm2 , what is the minor axis (2b)?
Answer:
The area of an ellipse is given by the formula: A = πab, where a is the major axis and b is the minor axis.
Given that the major axis is 10 cm (2a) and the area is 62.8 cm^2, we can set up the following equation:
62.8 = π(10/2)(b)
To solve for b, we can divide both sides of the equation by (10/2) and then divide by π:
b = (62.8 / (10/2)) / π
b = (62.8 / 5) / π
b = 12.56 / π ≈ 4 cm
So, the minor axis is 4 cm.
Draw a line with 40mm long , Then redrawe the following scales in each scale, briefly describe the relation ship between the full length of a line and a new line You drawn A 1:2
Answer:
Explanation:
The full length of the line is 40mm. In a 1:2 scale, the new line would be 80mm long. This means that for each 1mm of the original line, you need to draw 2mm on the new line. Therefore, the relationship between the full length of the line and the new line you drew is that for each 1mm of the original line, you need to draw 2mm on the new line.
if a simple machine requires an effort force that is less than the force of the load being moved, then the simple machine exhibits.....
A. mechanical advantage
B. rotary motion
C. linear motion
D. static equilibrium
if a simple machine requires an effort force that is less than the force of the load being moved, then the simple machine exhibit A. mechanical advantage
What is Mechanical Advantage?The force amplified by utilizing a tool, mechanical device, or machine system is known as mechanical advantage. To achieve the desired output force amplification, the gadget trades off input forces against movement.
The law of the lever serves as a paradigm for this.
Hence, it can be seen that there is a required effort for the simple machine to move and this has to be less than the force of the load being moved, this has the characteristics and features of mechanical advantage.

Consider the deflection (based on choices of E and I) and the weight of the material. How would you find a balance between the needed structural performance and weight?
Finding a balance between structural performance and weight is a trade-off that engineers often have to consider when designing structures. In terms of deflection, the modulus of elasticity (E) and the moment of inertia (I) of the material are important factors that affect the structural performance of a structure. A higher E value indicates that a material is stiffer, and a higher I value indicates that a material is more resistant to bending.
The weight of the material is also an important factor to consider, as it affects the overall weight of the structure, which can have an impact on the cost and ease of transportation, assembly, and maintenance of the structure.
One approach to finding a balance between structural performance and weight is to use a material with a high E and I value, while also being lightweight. For example, using a composite material made of carbon fiber reinforced plastic (CFRP) can provide a high E and I value while also being lightweight.
Another approach is to use a combination of materials. For example, using a lightweight core material such as foam and sandwiching it between two stiffer and stronger materials such as aluminum or steel. This can provide a balance between structural performance and weight, as the core material provides the necessary strength and stiffness, while the outer layers provide the necessary support and protection.
Additionally, engineers use optimization techniques such as Finite Element Analysis (FEA) to determine the optimal design, thickness, and orientation of the material to minimize weight while still maintaining structural performance.
Ultimately, finding a balance between structural performance and weight is a design decision that depends on the specific requirements of the structure and the priorities of the project.
