Suzanne is a recent chemical engineering graduate who has been offered a 5-year contract at a remote location. She has been offered two choices. The first is a fixed salary of $75,000 per year. The second has a starting salary of $65,000 with annual raises of 5% starting in year 2. If her interest rate is 9%, which should she take?
To satisfy desige limitation it is necessary to determine the effect of the 2- kN tension in the cable on the shear tension and bending of the fixed I-beam.
A 1 meter diameter cylindrical mass, M, is connected to a 2 meter wide rectangular gate. The gate is to open when the water level, h, drops below 2.5 meters. Determine the required value for M. Neglect friction at the gate hinge and pulley.
How will calculate the surface area of a rectangular open trench Length=100 mtr,Width=.6mtr,Depth= .75mtr.
