Consider the 20×60mm (h×b) bar with a 10-mm diameter hole which is made of steel with equal tensile and compressive yield strengths of 600 MPa. If we assume the material behaves with an ideal elastic-plastic stress strain response and the plate is initiallyfree of residual stresses, make a drawing of the stress distribution in the plane of the hole:a) When a tensile load of 200 kN is applied. b) When a tensile load of 400 kN is applied. c) After the 400 kN load is removed. d) What compressive load would you need to apply to make the material yield in compression?

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
