Chapter 6, Problem 73P

1. Determine the horizontal force P applied at the center which is necessary to start the wheel over the 5cm block. Also find the reaction at the block/ 2. If the force P may be inclined at any angle with the horizontal. Determine the minimum value of P to start the wheel over the block, the angle that P makes with the horizontal and the reaction at the block

Determine the force in member EF of the truss. Set P = 1,192 lb. Enter compression as a negative number and supply the answer in pounds. 500 lb -3 ft- -3 ft- -3 ft- E Dl 3 ft A B

Determine the maximum compressive force developed in member BG of side truss due to the right side wheel loads of the car & trailer. Assume the loads are directly applied to the truss and move from left to right. 23m 2kN DO 4kN 1.5kN2 H G A 3m B 3m C 3m D 3m E 4m

If the base plate carries a load of XX kN (including self-weight, which is equally distributed on the four corners), calculate the stress on the lower washers before the nuts are tightened. Analyse the stress in the upper and lower washers, when the nuts are tightened so as to produce a tension of YY kN on each bolt. Please refer appendix for XX and YY values.

A pair of 97-N forces is applied to the handles of the small eyelet squeezer. The block at A slides with negligible friction in a slot machined in the lower part of the tool. Neglect the small force of the light return spring AE and determine the compressive force P applied to the eyelet. 97 N 50 mm 42 mm OC B 17 mm 7.00 mm 97 N Answer: P = i -240.23 N
