The zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.

<h3>How would you identify zero-force members in truss?</h3>

You would definitely identify zero-force members in a truss by the fact that a joint has only two non-collinear members and there is no external load or support reaction at that joint, then those two members are zero-force members.

Zero-force members in a truss are the structural members that significantly support no loading but aid in the stability of the truss.

Therefore, the zero-force members in the truss are BE and BC. This is because they are the two non-collinear members.

Why should a toolpath be verified on the screen of a CAM system prior to creating the program code?
NISA [10]

Answer:

The tool's trajectory in a CAM program refers to the places where the tool will be during the work. It is important to review it before generating the program for the following reasons

1. analyze the machining strategy and identify which one is better for each piece.

2.Avoid the collision of the tool holder with the work piece.

3.Avoid the shock of the tool with the piece.

4. Prevent the collision of the tool with elements that are not displayed on the CAM such as clamping flanges or screws.

A disk shaped part is cast out of aluminum. Diameter of the disk = 650 mm and thickness = 16 mm. If the mold constant = 3.2 sec/
Natasha_Volkova [10]

Answer:

Time for solidification of the casting is 186 sec.

Explanation:

Chvorinov's rule is used to find the solidification time for any casting shape.

Step1

Given:

Diameter of the disk is 650 mm.

Thickness of the disk is 16 mm.

Chvorinov's rule constant is 3.2 sec/mm².

Step2

Calculation:

Total volume of the disk is calculated as follows:

V=\frac{\pi}{4}d^{2}t

V=\frac{\pi}{4}({650})^{2}\times({16})

V= 5309291.585 mm³.

Step3

Total surface area of the disk is calculated as follows:

A=\pi dt+2\times (\frac{\pi }{4}d^{2})

A=\pi \times 650\times 16+2\times (\frac{\pi }{4}\times 650^{2})

A= 696334.0117 mm².

Step4

Chvorinov's rule for time calculation is expressed as follows:

t=K(\frac{V}{A})^{2}

t=K(\frac{5309291.585}{696334.0117})^{2}

t=3.2(\frac{5309291.585}{696334.0117})^{2}

t=186 sec.

Thus, the time for solidification of the casting is 186 sec.
