For Nos. 42 to 44: The rigid bars AB and CD shown
in the figure are supported by pins at A and C and
the two rods. Neglect the weights of all members
and if the total vertical movement at the point
where P is applied will be limited to 5 mm,
determine:
42. The maximum force P which can be applied is
a.) 87,456 N
b.) 71,224 N
c.) 79,665 N
d.) 76,365 N
43. The total elongation of the steel rod is:
a.) 1.273 mm
b.) 1.557 mm
c.) 0.998 mm
d.) 1.442 mm
44. The total elongation of the aluminum rod is:
a.) 4.667 mm
b.) 4.363 mm
c.) 3.998 mm
d.) 4.112 mm
