AI Thread Summary
The discussion focuses on a student transitioning to a BEng in Aircraft Engineering who is struggling with matrix work, particularly in creating a stiffness matrix. They seek online resources for study materials rather than solutions to their homework. Recommendations include searching for books on Amazon using the term "stiffness matrix" and accessing educational links such as a summary on stiffness analysis from the University of Kentucky and Wikipedia's direct stiffness method page. The student is looking for guidance on where to find relevant information to aid their understanding. Overall, the emphasis is on finding quality resources to support their studies in matrix analysis.

To keep it brief I have had to change my degree to a BEng Aircraft engineering (year 4 hon

year), the main hiccup:confused::confused::confused: the crash course that I need to do for

matrix and one or two of the other subjects but it's the matrix work that I am struggling with .

I need material on line to help with my study the attached file is my homework i am doing at the moment

trying to make a stiffness matrix I don't want the problem solved just the info and where to get the info to solve it

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'
Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
