A bar is fixed to a support surface at the left end and loaded as shown with a known force F. Ignore any complications associated with the connection between the bar and the support surface. Given the variables material properties, cross-sectional area, and length, which ones can be used to determine whether the bar fails (yields) or not? Material Properties Length Total Area F Only total area and length, do not need material properties Only material properties and total area, do not need length All variables: material properties, total area, and length Only length and material properties, do not need total area The given variables are not enough to determine failure
