Problem No. 1: If the magnitude of š is 5 kN-m, determine the reactions on the pin support at š“ and the roller support at šµ. Solution:
Problem No. 2 : Bar š“š¶ supports two 400-N loads as shown. Rollers at š“ and š¶ rest against frictionless surfaces and a cable šµš· is attached at šµ. Determine ( a ) the tension in cable šµš·, ( b ) the reaction at š“, ( c ) the reaction at š¶. Solution:
Problem No. 4 : The bracket šµš¶š· is hinged at š¶ and attached to a control cable at šµ. For the loading shown, determine ( a ) the tension in the cable, ( b ) the reaction at š¶. Solution:
Problem No. 5: Determine the components of reaction at the fixed support š“. Neglect the thickness of the beam. Solution:
Problem No. 7: Draw the free-body diagram of the beam, which is pin-supported at š“ and rests on the smooth incline at šµ. Calculate the support reactions also. Solution:
