Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

Answer:
b = 73°
Step-by-step explanation:
Since SR and ST are congruent then the triangle is isosceles.
Thus the base angles R and T are congruent, so
b = 73°
Answer:
7
Step-by-step explanation:
2 = 2
4 = 2²
6 = 2 * 3
8 = 2³
adding the exponents of 2, we get 1+2+1+3 = 7
Answer:
Step-by-step explanation:
=1/4 x 3.6 + 54.3
= 0.9 + 54.3
= 55.2
