assume wood-plastic composite and that EF is 1‚000‚000 psi and Em is 175‚000 psi (HDPE for example)‚ then PF 6V F = PC 6V F + (1 − V F ) Then‚ PF/PC = 0.6 or 60% Strength – Unidirectional Continuous Fiber Lamina: In general‚ fiber failure strain is lower than the matrix failure strain. Assuming all fibers have the same strength‚ the tensile rupture of fibers will determine the rupture in the composite. Therefore‚ estimation of longitudinal

’Vincent is supposed to be weak. Yet his strength of character is the key to the story.’ Discuss. The film text ’Gattaca’‚ directed by Andrew Niccol can be seen as a piece that draws many parallels to the world that we live in today. One such parallel is the fact that often in society‚ the ones who are at a disadvantage are the ones who display the greatest strength of character. Niccol uses Vincent as the vehicle through which he demonstrates how strength of character can neutralise and overcome

MODULUS OF RIGIDITY Modulus of Rigidity Using the initial length‚ radius‚ measurements of torque and angle of twist‚ it is possible to calculate the Modulus of Rigidity for each specimen. The modulus of rigidity or shear modulus represents the ratio of the shear stress to the shear strain. It is denoted ‘G’. To calculate two separate values of G for each specimen‚ it is possible to use two methods. It is important to determine the polar moment of inertia to be used throughout the experiment:

1.Does the familial relationship between Daphne and Steve strengthen or weaken the control environment at Shear Madness? Explain In ways‚ family or close relationships within the workplace can be beneficial to the company by providing a family atmosphere. Employing close relationships can also help the company adhere to their core values. It can also be negative. The cost of using family can be substantially lower that hiring an outsider. However‚ with all good‚ this comes bad things. The
