(4) Calculate principal stresses σ and O₂ and find the principal planes. Draw a Mohr's circle with the stress. components of the inclined plane with angle values.

I need answers to questions 4, 5, and 6 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.

The figure shows a wooden model to reproduce a metal piece ofaluminum through the sand casting process.a) How much mass (g or kg) of aluminum do you need to melt?b) How much energy Q (Joules) is required? Assume an initial temperature of 50 ° C and a100% thermal efficiency.c) What dimensions will the final metal piece have? all is in cm

Please help. I need help with all 4 questions. Apply geometric tolerancing to part according to the instructions below. This exercise will provide you with experience in correctly applying and interpreting geometric tolerancing symbology. If you have trouble applying the symbols, page through this unit looking for similar examples. The Hole Bar in this unit is a good reference. Draw symbols and feature control frames clearly and neatly. 1. Establish all necessary basic dimensions. 2. Position the .250 hole within a diameter of .005 RFS relative to datum features A,B,C. 3. Position the three holes within a diamter of .012 at MMC relative to datum features A,B,C. 4. In the front view, identify the upper right corner as point "Y" and the lower left corner as point "X". Apply a profile tolerance of .020 between points X and Y relative to datum features A,B,C. Please refer to the attached image.

Calculate the Minimum Y distance on the drawing below: 1.000 O 2.000 O .460 O .510 1.966 O .500 C 2.000 Ø.995-1.000 6.00 0.008 MABC 3.000 Y 01.005-1.030 +0.005MABC B A .XX = .01 ANGLES= ± 1°

Select the correct statement regarding the solid model shown below. pattern1 It is easiest to create the 18 holes in this model by sketching each individual hole and using the extruded boss/base feature. It is easiest to create the 18 holes in this model by sketching one individual hole

How would you determine final dimensions using the plus & minus method for question  #D??
