Conclusion In the workshop‚ we are going to design a beam that will rupture when a load of 20 kg is placed at its mid-span region. We have made much consideration and preparation before the testing.

So‚ while it is possible to try to answer this question by discussing the moral issues‚ it is not easy to say whether euthanasia is ever morally supportable. Of course‚ euthanasia should be differentiated from simple removal of life support from a patient who has already effectively succumbed. The Churches‚ on good grounds‚ oppose euthanasia in all circumstances. We all regard life
