وممكن تعجلون شوي قبل يوم الاثنين علشن عندي اختبار 
نبدا على بركة الله.
a telephone pole issupported bya guy wire that exerts a poll of 200 lb on the top of the pole. if the angle between the wire and the pole is 50ْ what are the horizontal and vertical components of the pull on the pole
**
**
a boat is being towed through a cable that make s an angle of 10ْ with the shore . if the pull on the cable is 200 N , find the force tending to move the boat along the canal
**
**
Express in terms of the unit vectors i,j and k the force of 200 N that starts
3 -. at the point (2.5
and pass through the point (-3.2.1
**
**
determine the resultant of the three forces
f1 = -2.0 i + 3.3 j - 2.6 k lb
f2 = -i+5.2 j-2.9 k lb
f3 =8.3 i - 6.6 j +5.8 k lb
which are concurrent at point (2.2.-5
