Answer:
The shearing stress is 10208.3333 Pa
The shearing strain is 0.25
The shear modulus is 40833.3332 Pa
Explanation:
Given:
Block of gelatin of 120 mm x 120 mm by 40 mm
F = force = 49 N
Displacement = 10 mm
Questions: Find the shear modulus, Sm = ?, shearing stress, Ss = ?, shearing strain, SS = ?
The shearing stress is defined as the force applied to the block over the projected area, first, it is necessary to calculate the area:
A = 40*120 = 4800 mm² = 0.0048 m²
The shearing stress:
The shearing strain is defined as the tangent of the displacement that the block over its length:
Finally, the shear modulus is the division of the shearing stress over the shearing strain:
Answer:
Eyeglass lenses will almost always be convex on the outer surface, the one farthest from the eye, simply to fit it to the curvature of the face.

Answer:
266 g or 0.266 kg
Explanation:
The formula for specific heat capacity is given as,
Q = cm(t₂-t₁) ..................... Equation 1
Where Q = Heat Energy, c = specific heat capacity of Aluminum, m = mass of the aluminum fins, t₁ = initial temperature, t₂ = final temperature.
make m the subject of the equation,
m = Q/c(t₂-t₁)................... Equation 2
Given : Q = 2571 J, c = 0.897 J/g.°C, t₁ = 15.73 °C, t₂ = 26.50 °C.
Substitute into equation 2
m = 2571/[0.897×(26.5-15.73)]
m = 2571/9.661
m = 266 g or 0.266 kg
Hence the mass of the Aluminum fins = 266 g or 0.266 kg
<u>Answer:</u>
area of point has more pressure.
<u>Explanation:</u>
formula's : pressure = force ÷ area
1st pressure,
200 ÷ 0.2 = 1000 Pa
2nd pressure,
200 ÷ 0.004 = 50000 Pa
<h3>Therefore the pressure on the area of the point is more.</h3>
Answer: 0.321 seconds
Explanation:
Let assume that air has a temperature of 20 °C. Sound speed at given temperature is 
. As sound spreads at constant speed, time can be easily found by using this formula:
