when a particular metal is heated to 600 C its tensile strength drops by 50%. for every 5 C its temperature rises after 600 C, the tensile strength (decreases by 35%). this metal has a tensile strength of 280 MPa below 600 C and is used in the construction of industrial ovens. if the minimum safe tensile strength of this material is 38 MPa, what is the maximum safe temperature of the oven, in degrees Celsius?
