You, a person weighing 100 kg, are offered an opportunity to earn $10M (ten million $) by simply hanging from a rope for one minute. The rope is attached to the end of a glass sheet, 300 cm long by 10 cm wide by 0.127 cm thick (see figure below). Complicating the situation is the fact that: 1) The glass sheet contains a central, through thickness crack with total length of 0.162 cm that is oriented parallel to the ground. The fracture toughness of the glass is 0.83MPA m; 2) The rope is suspended 1.5m above a pit of deadly poisonous snakes. Would you care to try for the pot of gold at the end of the rainbow? (Your reasoning is required!
