Chapter 5, Problem 2P

B2

please i need her solving with using the formulas attached below of pin joint linkage

Find the reaction forces for the following problems

Q5

can you please write down each step clearly.

Solve both show all steps  and solutions

3. Figure 3 shows a brake pedal assembly from a car. Under the action of an applied foot force, the pedal lever acts against the fixed pivot and transfers load to the brake cylinder via an actuation rod. The pedal lever is of hollow section, three-sided form with section dimensions as shown in the figure (Section A-A). Via consideration of the pedal lever as a free body, calculate the reactions acting at the fixed pivot and the 10 mm dia. pin. (hint-take the pin and the pivot as supports) Draw the bending moment diagram for the pedal lever and determine the maximum tensile and compressive stresses arising if a force of 1.3 kN is applied at the foot pedal as shown in Figure 3. (hint -exclude the areas of the holes) [Ans ot = 134 N/mm² oc = 215 N/mm*] i. ii.
