Due to the use of varying FWT configurations, different wear mechanisms occur between the friction wheel and test sample.
A similar wear behaviour of alloys with included small WC is shown in  where a high resistance against pure abrasive loading with a rubber based FWT is recognized, but on the contrary they have low resistance if the load changes to high impact and the small carbides are removed from the alloy.

Although safer, a minority (the 1 male interviewed), is paid through commercial banks, as recipients need transport (R 14 or US $1.80 per return fare), to access commercial banks in the FWTs, and because bank charges will decrease their grants.
Structurally, childcare and subsistence rhythms hamper women's flexibility and mobility to seek work and/or educational opportunities - women often have no time, space and/or taxi-fare to seek work in FWTs.
