Instructions:
1. Answer the following questions and give them to your tutor before the end of your tute class.
2. Some questions will be answered in the lecture-tute as examples. These questions still have to be handed in.
3. Print the cover sheet from the last page of these tute questions, complete it and attach it to your submission.
PROBLEM 2/30
Determine the moment of the 800-N force about point A and about point O.
PROBLEM 2/50
(a) Calculate the moment of the 90 N force about point O for the condition  = 15 deg. Also, determine the value of  for which the moment about O is (b) zero and (c) a maximum.
PROBLEM 2/56
If the combined moment of the two forces about point C is zero, determine
(a) the magnitude of the force P
(b) the magnitude R of the resultant of the two forces
(c) the coordinates x and y of the point A on the rim of the wheel about which the combined moment of the two forces is a maximum
(d) the combined moment MA of the two forces about A.
PROBLEM 2/60
The indicated force-couple system is applied to a small shaft at the centre of the plate. Replace this system by a single force and specify the coordinate of the point on the x-axis through which the line of action of this resultant force passes.
PROBLEM 2/67
The 180-N force is applied to the end of body OAB. If , determine the equivalent force-couple system at the shaft axis O.
PROBLEM 2/77
Calculate the magnitude of the tension T and the angle for which the eye bolt will be under a resultant downward force of 15 kN.
PROBLEM 2/87
Replace the three forces acting on the bent pipe by a single equivalent force R. Specify the distance x from point O to the point on the x-axis through which the line of action of R passes.
PROBLEM 2/91
The design specifications for the attachment at A for this beam depend on the magnitude and location of the applied loads. Represent the resultant of the three forces and couple by a single force R at A and a couple M. specify the magnitude of R.
