Part A
LA = 15 m
zA = 6 m
wA = 8 kN/m
Part A - There are 6 questions in this part Refer to your email from Tim which defined values of the different variables. Consider a simply supported beam of length LÀ m. There is a UDL of magnitude WA kN/m which acts vertically downwards along the entire length of the beam. There are two additional vertical downwards point loads, each of magnitude PA = WALA, one acting at a distance ZA M along the beam (as measured from the left support), and another acting at a distance ză m along the beam (as measured from the right support). Before attempting this question, draw a diagram of this beam and the loading (you do not need to submit the diagram, but it will help you). If answers are negative, make sure you enter the minus sign with your answer.

Question 1 0.5 pts Question A1 What is the vertical reaction at the left hand support in kN? Question 2 0.5 pts Question A2 What is the vertical reaction at the right hand support in kN?

Question 3 1 pts Question A3 What is the value of the shear force at the mid point of the beam (in kN)?

Question 4 1 pts Question A4 What is the value of the maximum bending moment (in kNm)? Note if there are both positive and negative moments, give the value and sign of the highest value - eg if you have +10 and -20, your answer should be -20; if you have +20 and -10, your answer should be +20. Question 5 1 pts Question A5 What is the value of the bending moment (in kNm) at a position infinitesimally to the right of the first point load (ie at a position only very slightly greater than ZA m along the beam (as measured from the left support))?

Question 6 2 pts Question A6 What is the value of the shear force (in kN) at a position infinitesimally to the right of the first point load (ie at a position only very slightly greater than ZA m along the beam (as measured from the left support))?
