Question

1. Fundamentals of Engineering Exam style (5 points each): Given the following 5-cm diameter shaft with the rectangular beam (2-cm by 5-cm) attached to the end: 2000N LA 2011 Im steet shaft i. The normal stress at point A located at the top of the shaft is: a) 392 MPa b) 345 MPa c) 326 MPa d) 247 MPa ii. The shear stress at point A located at the top of the shaft is: a) 120 MPa b) 81 MPa c) 42 MPa d) 86 MPa iii. The stress state at point A is described by which element?

Answer 1

1 2000N 1 2000N 2000X15 2000 Nim o 2000nam a HOM= 2000* q = 4000 Nm 6 Normal stress at 6 8= MC = 4000X103( 32 = 325.549/326 MPa] II (50)4 ② shear stress at A T- I - 2000 x103x (SP) I (50)4 81 MPa - 81.48
