Answer:
a) True
b) False
c) False
d) True
e)False
Step-by-step explanation:
a) True because Since it is non-empty and it is bounded maximum of A is an upper bound and hence contains supremum
b) False because Suppose A to be the interval (0,1) and L= 1. Then clearly supA= 1 < 1 = L
c) False because Let A= (0,1) and B = {1} it shows that Sup A =1 = Inf B
d)True
e)False because lets Take for both A and B the interval (0,1). it is easy to see that supA ≤ supB, but no element of B is an upper bound for A.
Answer:
54.8 Nm
Step-by-step explanation:
Torque is the cross product of the radius vector and force vector:
τ = r × F
Another way to write it is the product of the radius and force magnitudes times the sine of the angle between the vectors.
τ = rF sin θ
Here, r = 0.366 meters and F = 155 Newtons. F is in the +y direction, and r is 15° below the +x axis, so the angle between the vectors is 90° − 15° = 75°.
τ = (0.366 m) (155 N) (sin 75°)
τ = 54.8 Nm
