THE UNIVERSITY OF TEXAS AT AUSTIN Department of Aerospace Engineering and Engineering Mechanics EM 306 STATICS - UNIQUE NUMBER 14040 Fall 2008 QUIZ #1 Name: Date: Given are two ropes that act on the hook of the figure on the left. The magnitudes of the forces exerted by the ropes are known. At what angle θ must the 800-lb force be applied in order that the resultant R of the two forces has a magnitude of 2000lb ? For this condition determine the angle β between R and the vertical axis. SOLUTION:

THE UNIVERSITY OF TEXAS AT AUSTIN Department of Aerospace Engineering and Engineering Mechanics EM 306 STATICS - UNIQUE NUMBER 14045 Fall 2008 QUIZ #1 Name: Date: It is desired to remove the spike from the timber by applying force along its horizontal axis. An obstruction A prevents direct access, so that two forces, one 1.6KN and the other P , are applied by cables as shown. Compute the magnitude of P necessary to ensure a resultant T directed along the spike (i.e. on the horizontal axis). Find also the magnitude of T . SOLUTION:
Department of Aerospace Engineering and Engineering Mechanics EM 306 STATICS - UNIQUE NUMBER 14050 Fall 2008 QUIZ #1 Name: Date: In the design of a control mechanism it is determined that rod AB transmits a 260-N force P to the crank BC. Determine the scalar components P t and P n of P , which are tangent and normal, respectively, to crank BC. SOLUTION:
