A critical component for a mechanical system will be subjected to a 0.01 Hz cyclical stress during operation (0.01 cycles per second). The stress will fluctuate between a tensile load of 150 MPa and a compressive load of -250 MPa. The design calls for a survival confidence limit of 10% (i. e. 10% failure rate acceptable). Approximately how long, in days, can the component be used before it must be replaced during maintenance

What is the momentum of a 2 kg object moving at 15 meters per second

The slope of a velocity time graph over any interval of time gives the during that interval

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
