A rectangular plate is 3.0 m by 10.0 m. It is fixed along the two shorter edges and one of the longer edges to a rigid wall. At 25 ºC, there is a gap of 8.0 mm between the other edge and a fourth rigid wall. The temperature of the plate is suddenly increased by 40 ºC, and is held at this temperature for 15 hours. The elastic plate has a modulus of 200 GPa, Poisson's ratio of 0.30, and a thermal expansion coefficient of 30 x 10-6 /ºC. The creep law for the material is given by where the von Mises effective stress is in MPa

Answermuch larger;

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
