Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra =
Ra =
= 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb =
Rb =
=
units
Adding these two vectors A and B together, magnitude of vector R is
R = 
R =
= <em>10.09 units</em>
Answer:
T = 540 N (to two significant digits)
Explanation:
Let the crate dimension L be from strap attachment to floor contact
Let T be the strap tension
sum moments about the floor contact point to zero
mg[½Lcos25] - Tsin61[Lcos25] + Tcos61[Lsin25] = 0
L is common to all terms, so divides out.
½(71)(9.8)cos25 = T(sin61cos25 - cos61sin25)
T = (71)(9.8)cos25 / (2(sin61cos25 - cos61sin25))
T = 536.428020...
