Acylindrical specimen of a brass alloy having a length of 92 mm (3.622 in.) must elongate only 4.60 mm (0.1811 in.) when a tensile load of 93000 n (20910 lbf) is applied. under these circumstances what must be the radius of the specimen? consider this brass alloy to have the stress-strain behavior shown in the animated figure 7.12.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
